Using Wayland and 2 monitor setup. If the running apps and your fullscreen OpenGL/Vulkan app are on the same screen, clicking their icons on the taskbar will usually return you back to the fullscreen program that is running. STEPS TO REPRODUCE 1. Open one or several OpenGL/Vulkan program(s) in full screen (e.g. Stellarium, Steam game with Proton). 2. Press Win key to make the taskbar and menu visible 3. Try to click on some other app (e.g. Spotify) 4. Notice it will return you back to the Stellarium/Game 5. This happens with left mouse button - the right one works and opens setting menus. OBSERVED RESULT Not registering the click with the mouse left button. However, If the app is on the 2nd monitor, clicking the icon on the taskbar will make that app visible on the screen, but OpenGL/Vulkan will steal the focus again, so you will be back to the game/program. EXPECTED RESULT Registering clicks and shifting focus to desired app. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.113.0 Qt Version: 5.15.11 Kernel Version: 6.6.7-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 3700X 8-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: AMD Radeon RX 6650 XT Manufacturer: Micro-Star International Co., Ltd Product Name: MS-7C02 System Version: 1.0
Cannot reproduce with Stellarium on Plasma 6 Wayland.
(In reply to Nate Graham from comment #1) > Cannot reproduce with Stellarium on Plasma 6 Wayland. Well maybe it's a non-issue on P6, but I'm still on a stable P5. Also, if you have, try some Steam game running Proton fullscreen. That's where I get this issue the most.
Unfortunately I still cannot reproduce this issue in current git master, which is about to become Plasma 6.3. Are you still able to reproduce it in a recent version of Plasma, like 6.2.5 or later?
you're right it doesn't happen anywhere in the Plasma 6.
Thanks for following up!
