When I want to close some running program sometimes a popup window appears asking me to confirm. Only the windows decoration of this popup is shown and the content is invisible . It is also frozen Please see the screenshot Reproducible: Always Steps to Reproduce: 1. open Konsole 2. run 'top' 3. press alt-f4 to close the window inisible pop apears waiting for confirmation Actual Results: frozen popup window with just a window frame and windeco visible. see the screenshot Expected Results: working popup window it is easy to reproduce when You want to close an application that is working on something - then KDE tries to get confirmation that You really want to interrupt the app. If You leave the popup untouched after 3 minutes it unfreezes

Is that only a problem with Konsole or do you also experience it with other applications? Can you please post the output of: qdbus org.kde.KWin /KWin supportInformation
This is for basically happening every system "confirmation request" pop-up. I mention Konsole just to have en easy to reproduce scenario
> Can you please post the output of: > qdbus org.kde.KWin /KWin supportInformation It doesn't actually look like the compositor is running at all (hard to say on the particular setup, but the round corners are crisp and I see no shadows) "Freeze" also does not seem to imply that kwin turns inresponsive - at least it looks as if you can still move around windows, yesno?
I checked what You suggested, it seams the composer was not started by the default. not it seams to work. Is it possible to run KDE without composer as long as I don't have popups? - I don't really understand it. About freeze - it froze for about 3 minutes - during this time all the windows passing the area of the konsole were distorted - as in my 2nd attachment screenshot.
This is not a kwin bug, but please attach the output of glxinfo (to provide a hint on why compositing may fail) There's most likely a window (the dialog?) with uninitialized content which also doesn't update for exposure events and by this accumulates everything the server ever displayed in its area. Whatever client provides this window is likely "frozen" (taken by something) For a wild guess, try setting the system language to english.
actualy when I tried to change language to english - confirmation popup caused the same freeze....
Created attachment 100812 [details] glxinfo as requested
I think I found the reason for the freeze. Sound system on HP G2 Laptop sometimes does not detect the sound card. Then the popup should theoretically generate system sound but if sound system fails than the window keeps waiting for it to complete . Maybe the system should not wait until invoke finishes?
