Created attachment 112967 [details] A preview of both The Plasma OSD popup that shows up when changing the volume or to an external display (Super+P) starts to flicker most of the time when fading out if it's overlapping a window partially (not when it does so entirely), or if it overlies multiple windows.
I can reproduce this bug quite often, although for me it can also happen while the OSD is dead centered in front of a window so not just when there is overlapping. KDE Plasma Version: 5.12.5 KWin Version: 5.12.5 KDE Frameworks version: 5.46.0 Qt Version: 5.10.1 OS: Manjaro GPU Driver: intel

Here is the proof I can offer for the flickering even when there is no window overlapping: https://youtu.be/-Scsx3hg0zI Sorry for the mobile phone recording - whichever screen recording program and presets I use, the windows flicker crazily in the recording (but not when actually shooting the video).

In both cases the detection of vsync seems to not work, which I think is the main issue here. For the nouveau user I suggest to switch to the proprietary Nvidia driver. It's still better.

It's still better. by the way i don't know if it helps but i had sync to vblank and force full composition pipeline turned on in the nvidia settings
I have not observed this since switching to 5.13. Maybe it was a bug with the old blur effect, who knows.
me neither, i think it's gone, i'm gonna mark this as resolved
