SUMMARY They are multiple applications which are not showing their content anymore, on both Wayland and Xorg (X11). On wayland it is just black, and on X11 we see what was behind the window when it has open itself. It is not the case for many applications, just for some of them. And it is also the case for some stuff (pop up, menu) appearing on top of applications. It seems related to some hardware, as this bug appear on my tower and not on two laptop (all running the same OS with the same version). It's like that since something like a week. EXAMPLES CASES This bug appear on the full window of Discord and Spotify (both using Flatpack). It appear on all the menu of Brave (Flatpack) but not his window itself. I don't know if it is related but the Firefox version distributed by "KDE neon" also doesn't work and is completely purple (not the same behaviour so it doesn't seem to be the same issue). The Flatpack version of Firefox has not any issue. LibreOffice is affected differently, so maybe his bug is not related. It doesn't work on X11, still showing a bit of text where other application don't show anything. And it work fine on wayland. The bug doesn't appear on most app : System setting, Discover, Firefox flatpack, VLC ... STEPS TO REPRODUCE 1. On a computer (hardware) affected with the bug, Just open an Application affected by the bug (like Discord). 2. See that the content doesn't show up anymore. OBSERVED RESULT On wayland the window of an affected application is just black. On X11 the window of an affected application show what was behind the window when it has open itself. When moving the mouse over the application, the cursor can change depending of where it is, like if the content of the window was still here. See pictures for how it looks like. EXPECTED RESULT We should be able to see the ordinary content of each application.

(In reply to Dilam from comment #7) > Created attachment 158291 [details] > How the bug appear when right clicking on the Discord icone on Wayland The right clic on the Discord Icone is back to normal, on both Wayland and X11. I don't know how to delete this image from the list. Everything else is still not working : Discord window, Spotify window, LibreOffice on X11, and Brave pop-ups (right clic and menus).

There are 5 different cases : - Everything working as normal. - The application window not showing anything : black on Wayland, and show what was behind on X11. Examples : Discord on Spotify. - The application showing some stuff and not everything, on both Wayland and X11. Examples : Gimp. - The application showing some stuff and not everything on X11 and working fine on Wayland. Examples : All the libreOffice suite and Inkscape. - The application window appearing normal except that every pop-up are empty (just flat color). Examples : Brave pop-up, and Steam pop-up integrated in games (appearing with shift+Tab in a game, not the window dedicated to Steam).
Everything is fixed with the last update I made. 👍 (I maybe did the update a bit late because it has not shown that there are updates with the icon in the task bar. I saw it only when opening Discover for something else.) In System info there is only one thing that has changed : Kernel Version is now 5.19.0-41-generic (64-bit) (instead of 5.19.0-40-generic (64-bit) ).
