Hi Dialogs under kwin_wayland SOMETIMES vanish into nothingness leaving applications stuck regardless the app (firefox, libreoffice, kwrite) .. dialogs "appear invisible" .. they open active to the parentwindow but dont show up :-o ( leaving its parent-app stuck in a .. lets say "SaveAs"-dialog ) ( this produces no logs ) they only way to move on is to kill the app The dialog doesnt show up as an windows , nowhere to find ... however in pagermoder (show all apps) the dialog leaves an empty spacer for the dialog (which is not activateable) i tried to close the assumed "SaveAs"-Dialog spacer ( red [x] in pagermode ) resulting in a crash of kwin_wayland and all withit (coredump and logexerpt attached) thanks for support -c-

This BUG does also affect "new windows" in general ... if they dont show up i can mostly close them with Alt+F4 , restarting plasmashell .. and then mostly it returns to expected behaviour .. i tried to find out howto debug the kwin-wayland-session , installed some according debuginfo-packages, but that doesnt improve loggin .. how can i provide useful information to this ?
You can try using the environment variable WAYLAND_DEBUG to get more output. But I fear the problem is somewhere else in the stack. Could you please provide the output of qdbus org.kde.KWin /KWin supportInformation

Shot in the blue: please try disabling the dim inactive effect.
(In reply to Martin Flöser from comment #9) > Shot in the blue: please try disabling the dim inactive effect. i disabled effects "dim inactive" and "dim parents" .. -> no change
I also experience this issue but I've never seen this happen to wayland clients. Only for xcb / x11 windows such as firefox, itellij-idea, kmail as xcb window etc. This effects every such window (including dropdown menus). Amateur description: It looks like some rendered frames are skipped at the beginning of a window lifetime. The started program still works ("headless"), but it has lost visual connection with compositor. Also when compositor is running several hours, these issues are happening more often. I'm on Intel graphics, Plasma 5.17.4, KF 5.66.
