Created attachment 115978 [details] video SUMMARY Rendering defects appear in blurry windows, menus or popups when on top of one or more GTK windows. STEPS TO REPRODUCE 1. (Not always reproducible.) Run a GTK application (for my purposes it was Spotify) and another larger GTK application on top of it (to increase your chances of the bug appearing). 2. Run a KDE window (Konsole with blur on) or pull open a panel menu (Kicker or Kickoff) or popup. 3. If you are using Spotify or Lollypop, start switching between audio tracks, this makes it appear sooner. OBSERVED RESULT There are rendering defects present in the overlaid blurry windows that correspond to the borders of the underlying non-maximized GTK window(s). EXPECTED RESULT The blurry windows are unaffected by the underlying windows. SOFTWARE VERSIONS KDE Plasma Version: 5.14.2 KDE Frameworks Version: 5.51.0 Qt Version: 5.11.2
Can you reproduce it with Qt apps?

Judging from the video, it looks like STEPS TO REPRODUCE has some missing steps, e.g. did you have Spotify unminimized before you started recording the video? Could you please provide more detailed screencast? It would help with reproducing the bug. Also, could you please use Lollypop? Even though Spotify says "Music for everyone", that's a lie.

Spotify was unminimized when I started recording the video. (This bug is already very difficult to reproduce as is, but if you use Spotify free I'm fairly certain you'll encounter it.) What do you mean by a more detailed screencast? I'm going to try Lollypop but I'm not convinced I'll be able to reproduce it with Lollypop.
(In reply to Rooty from comment #4) > but if you use Spotify free I'm fairly certain you'll encounter it.) In some countries, Spotify is not available. --- Well then, I'll try to reproduce it with Lollypop.

Should you decide to use Spotify anyway, I created a dummy account for you, email: ceavowro@wegwerfemail.de password: spotifykde You should be able to log in without a VPN. It works for 14 days then you have to log in just once using a VPN and you get another 14 days. They listed the repositories for the package here: https://www.spotify.com/us/download/linux/ It's also in the AUR.
Thank you for the account, but that would be probably violation of ToS. I'll try to reproduce the bug with Lollypop or some other GTK apps.
