The purpose of this page is to provide information on known Adobe bugs affecting use of UXP panels.

Make sure you are running the latest version of Photoshop (old bugs which have been fixed will be removed from this list). Be sure to also separate information on how to install from a downloaded CCX file (for Lumenzia, etc) or how to install from the Adobe marketplace (for Web Sharp Pro).

Known issues (anything marked as UXP-related means that a Photoshop update will probably be required to address the issue):

• Lumenzia installs but then goes missing when you restart Photoshop. This occurs because you have an older version of thep plugin installed which is not compatible with the latest version of Photoshop and then installed a new version of the plugin which supports it. PS sees both and rather than launching the correct version or removing the old one, it removes the new version and what's left won't launch in your new version of Photoshop.
  Workaround: Manually delete the older version of the plugin (or rename it, such as by adding "BACKUP" to the folder name). The folder can be found in:
  - MacOS: /Users/{yourUserName}/Library/Application Support/Adobe/UXP/Plugins/External/_______
  - Windows: C:\Users\{yourUserName}\AppData\Roaming\Adobe\UXP\Plugins\External\_________
  - The last folder (______) will be an ID for the plugin and the version number. So you will see dddd1010_##.##.## for Lumenzia (the ID is "0a4bb5cd" for Web Sharp Pro or "3ecc70be" for my free sharpening panel).
  
• Panel shows as installed in the Adobe installer, but is not listed under the Plugins menus in PS. This could be the previous concern, but can also occur if you launch PS under "Rosetta" in MacOS. Solution: Avoid Rosetta, Adobe does not support it for hybrid UXP plugins, and it causes PS to run at half speed. If you are using Rosetta because you have some old CEP plugin, you should find a UXP replacement or stop using that plugin. CEP is obsolete - support was effectively dropped with the launch Photoshop 2021.
  
• None of the buttons work. This may be caused if file permissions are corrupted for plugin data (which may occur after some PS updates). Workaround: Uninstall and re-insall the plugin (go to Plugins / Manage / ... to uninstall). You may wish to first backup the plugin data, as uninstalling will reset all panel preferences / templates. The folder can be found in:
  - MacOS: /Users/{yourUserName}/Library/Application Support/Adobe/UXP/PluginsStorage/PHSP/25/External/_____/PluginData
  - Windows: C:\Users\{yourUserName}\AppData\Roaming\Adobe\UXP\PluginsStorage\PHSP\25\External\_________\PluginData
  - Where PSPH may be BETA for PS beta, the number will be the major version of PS you're using, and ____ will start with 0a4b for Web Sharp Pro, 3ecc for Web Sharp (free panel), dddd for Lumenzia.
  
• Panel is not automatically visible after installing or launching from CCD. This is a known MacOS bug which has been reported to Apple. Workaround: Look under Plugins menu in PS (required if you installed while PS was closed), or click <TAB> twice to hide all panels and then show again.
  
• The panel will not start. This may be caused by PS being unable to write to data folders (probably some kind of permissions issue in Photoshop, CCD, or UPIA which is not showing any clear error for the user). Workaround: close PS, delete the PS folders for panel data, and restart PS. This will allow it to regenerate folders with proper permissions:
  - The simplest way to achieve this is to uninstall and reinstall the plugin. However, this will delete all panel preferences / settings. If you prefer to keep settings (often very helpful for Web Sharp Pro), follow the next steps to copy your data before deleting the data folders, and then you can copy the files back.
  - On Mac, click <cmd>-<shift>-<period> to show hidden folders and navigate to /Users/ {{ your user folder }} /Library/Application Support/Adobe/UXP/PluginsStorage/PHSP/ {{year of PS installed} /External
  - On Windows, navigate to C:\Users\ {{ your user folder }} \AppData\Roaming\Adobe\UXP\PluginsStorage\PHSP\ {{year of PS installed} \External
  The "AppData" folder is hidden on Windows, so either paste this location into the File Explorer (be sure to update the user name), or go to the view options in the file explorer and make sure "hidden files" is checked to see it.
  - Move the contents of this "External" folder somewhere else (such as to the desktop, so you can restore later if desired) and then delete the External folder. "External" is where Adobe puts all the 3rd party data for UXP plugins, and it will contain one or more strangely named sub-folders for each panel
  - The "dddd1010" folder is for Lumenzia, "0a4bb5cd" folder for Web Sharp Pro, "3ecc70be" for the FREE free version of Web Sharp.
  - After deleting that folder, restart PS and the folder should be recreated (but this time with proper rights and the panel should work). If it still does not work, try deleting at a higher level (such as the 23 or PHSP). PHSP is a reference to "Photoshop" (as opposed to other Adobe applications which would have other 4-letter designations). The number "23" here is for the version of Photoshop, which is one greater than the year (v23 is PS 2022, etc). So this link would end in 24\External, 25\External, etc for future versions of PS.
  - If still failing, be sure to check that you don't have any anti-virus or other defensive software which may be blocking Photoshop's ability to read and write these folders.
  
• Vertical text alignment for Lumenzia buttons are spaced out or significantly off-center. This is a rare PS bug specific to Windows. The underlying issue appears to be use of some 3rd party fonts. I am unclear exactly why these fonts cause conflicts with UXP and whether the fonts may be updated to avoid this or if a future PS update may be able to resolve the issue. Users have reported conflicts with a few different fonts (several have reported conflicts with Anthoni Signature from DaFont, one person reported Amalfi Coast from DaFont, and one person reported Anisha Modern from Envato). I am unclear what the common factor may be, but it would appear that several fonts might trigger this issue with the current versions of Photoshop.
  Workarounds include:
  - Best option: Remove the conflicting font. You can move all possible fonts out of the installed location and restore them in groups to help quickly find the responsible font. Restart PS after any font changes. Or you could try to reset all fonts to defaults (be sure to back up your fonts first). Note that resetting fonts may not work, as this does not necessarily remove 3rd party fonts.
  - Alternative if the font fix fails: Go to the flyout menu in my panel (top-right three bars icon) / Utilities and look for a couple options in the right-hand column to help fix alignment. This is quick and easy and avoids the need to remove fonts, but does not resolve the issue for all users (probably either depending on the font, or the possibility that there are triggers other than fonts for this issue).
  
• Dropdowns do not work. This is a rare issue affecting some Windows users. Potential workarounds:
  - Click on the dropdown, then use arrow keys, then click <space> to choose the option (you won't see it, but using arrow keys should still help select from the hidden options). You may have to try a few different variations of arrow keys to know you're not' selecting the same item blindly, so try up and down separately.
  - Try right-clicking a button in the main panel a couple times to toggle tooltips, this may reset the behavior where PS is hiding the dropdown behind the dialog.
  - Another potential workaround is to use File / Open in PS, which may also reset the behavior in PS.
  
• A progress bar may appear while you are supposed to be working interactively with the panel (such as interactive cropping, responding to a dialog with options, entering an interactive radius for sharpening, Color Range, Content-Aware Fill, etc), resulting in the interface appearing to be stuck or unusable. Workaround: Click on the dialog (not the progress bar) to put focus on it. This will generally allow interaction with visible elements (Sky Replacement is very limited if you have selected a sky as the dropdown won't close), as well as ability to click <ESC> or the red X to close a popup without having to force-quit Photoshop.
  If truly stuck, please sampling the Photoshop process on MacOS (https://support.omnigroup.com/sample-osx/) or get a process dump on Windows: (https://support.plex.tv/articles/201373203-gather-a-process-dump-or-sample-process/) and send to me to forward to Adobe for review. This information can show the developers where things are getting stuck.
  
• Adobe's list of known UXP issues may be seen at https://developer.adobe.com/photoshop/uxp/2022/uxp/known-issues/
  
• Note that if any of the above workarounds are insufficient, you may also install Lumenzia v9 as a workaround (v9 requires Rosetta for M1+ users).

*** To downgrade Photoshop: Open the Adobe Creative Cloud Installer / All Apps and click ... next to Photoshop for "other versions" to install and older version.

If your plugin is installed in CCD but does not show in the Plugins menu of PS:

• First, look under the "Plugins" menu of PS, where the newer UXP panels are found. [Note: Windows / Extension (legacy) only applies to older CEP panels. All of Greg's panels are now available as UXP panels and this panel is only meant to provide support for the UXP version of the panels.]
• Please check that you are running a version of PS which supports the minimum requirements for the panel (Lumenzia and Web Sharp Pro currently support v23.0, but will soon require v23.3). The easiest way to check is to update to the latest version of Photoshop and make sure you are launching that new version (you can have older years of PS installed at the same time). Look under Help / System Info to confirm the version of PS.
• Try repairing CCD ("Creative Cloud Desktop", same Adobe installer used to update PS itself). Next to CCD should be an uninstall program. Run that and choose the "repair" option (no need to uninstall it).
• Try reinstalling the plugin. This may reset all plugin data (causing loss of any custom settings or templates), so be sure to back up your plugin data first. Go to the top-right flyout menu in Greg's plugin and choose Utilities / Export panel data to create a backup. Once you've backed up, go to Plugins / Manage in PS to show installed plugins in CCD, then click ... to uninstall, and then install again normally (using the CCX from the ZIP download for Lumenzia or downloading from Adobe for Web Sharp Pro).
• If still stuck, please contact [email protected].

Photoshop beta (help get bugs fixed!)

If you are affected by a bug in Photoshop, one of the best ways to help ensure it gets resolved quickly is to participate in Adobe's beta program. This is VERY easy to do (no more complicated than downloading any version of Photoshop, and it is separate from your official version of Photoshop so that you can launch either and avoid any problems you find in the beta).

Install the beta simply by opening the Creative Cloud Desktop (CCD) app (where you install and update Photoshop normally), then go to the "beta apps" section of the list on the left to install the Photoshop beta. You can watch a video of the steps here: https://helpx.adobe.com/x-productkb/global/creative-cloud-beta.html#video

Note: Be sure to enable automatic updates for the beta. In CCD, go to preferences / apps and make sure you see the blue toggle on Photoshop (beta). New releases come out roughly every 2 weeks.

You can provide feedback directly to Adobe engineering from the beta by clicking the "beaker" icon at the top-right of the beta.
