Hi,
when updating from 5.14 to 5.15 on a system with NVIDIA GP108 [GeForce GT 1030] (NV138) and Ryzen 9 3900XT using kde/plasma on X (not wayland), there is a regression: There is now some annoying black flickering in some applications, for example thunderbird, firefox, or mpv. It mostly happens when scrolling or when playing video. Only the window of the application flickers, not the whole screen. But the flickering is not limited to the scrolled area: for example in firefox the url and bookmark bars flicker, too, not only the web site. I have bisected the issue to this commit:
commit 3e1ad79bf66165bdb2baca3989f9227939241f11 (HEAD)
I have been experiencing this same issue since switching to 5.15. I can confirm that reverting the above mentioned commit fixes the issue for me. I'm on GP104 hardware (GeForce GTX 1070), also running KDE Plasma on X.
Cheers,
