UPD. Window decorations of McMojave theme also get broken - they stop rerendering when making windows active/inactive or when windows are resized. Not sure if this issue related to the bug and if this is KWin's issue and not theme's.

This bug report is pretty old, sorry that we couldn't get to it sooner. I assume it's no longer relevant; if it still happens on Plasma 6, just reopen this and we'll take a look

Thank you for taking a look nonetheless. It's indeed not relevant anymore to me since I've changed my GPU. But if there is any interest, I can install this older card and check whether the bug can be reproduced.
