The title pretty much says it all. Installed 22.4 on Windows 10 today, and all the docking icons for third-party extension panels, plugins, and even Adobe's own Plugins panel are missing. Totally blank. The plugins listed inside the Adobe's plugins panel have their corresponding icons, but the docking icons for when these items are in a panel dock are gone. The docking icon for the Adobe Color Theme's panel is also missing. There may be others. I've not checked every Adobe panel. An icon-less panel dock is not very useful.
