Just came here to report the same thing, so I can confirm this does indeed happen in the Plasma Wayland session, using Nvidia's proprietary driver. Currently on version 510.54, but I've observed this on older driver versions (with support for the GBM backend). It only happens with the "Background Contrast" effect on, "Blur" does not affect it at all. In the X11 session, it works perfectly. A bit of info about my environment: SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux, Linux Kernel 5.16.16-zen1-1-zen KDE Plasma Version: 5.24.3 KDE Frameworks Version: 5.92.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION CPU: Ryzen 5 2600 GPU: Nvidia GTX 1060 6GB Nvidia Driver 510.54
Oh also, moving this to kwin/wayland-generic as I think it's more of a kwin issue. No worries tho, I'm always unsure of these categories myself. I had to check with the kde-bugs channel to make sure this change was ok, in fact 😁
This should be fixed with https://invent.kde.org/plasma/kwin/-/merge_requests/2358 which I believe is set to be in 5.25
