Created attachment 118875 [details] screenshot XRender Before update from 5.15.1 to 5.15.3 it was without problems. CPU Intel, GPU Nvidia 940MX, drivers 410, 418, no difference.
When intel GPU is choosen and PC rebooted, the bug remains (still occurs, the plasma is still monochrome).

You enabled the gray scale effect (kwin4_effect_grayscale).
Well... no, I didn't .) Thank you for clarifying this, but there is no chance I ever enabled it. Why would I do that? :)
(In reply to Tom Kijas from comment #10) > Well... no, I didn't .) Thank you for clarifying this, but there is no > chance I ever enabled it. Why would I do that? :) Hmm, in this case it could mean two things: * either machines start uprising against human race * or someone decided to prank you In either case, open Desktop Effects, search for "Grayscale" effect and disable it.
Yeah, because it would be totally strange if by update something goes wrong ;) Noone has access to my PC.
KWin doesn't provide the greyscale effect. You either installed it manually or your distribution.
