SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux 5.14.2
(available in About System)
KDE Plasma Version: 5.23.0
KDE Frameworks Version: 5.87.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
GPU NVIDIA GeForce GTX 660 with proprietary NVIDIA driver 470.74
It is known that NVIDIA driver doesn't preserve graphic context on supsend, so everything needs to be redrawn.

I think this bug is also related to kwin.

Just in case, I've reported this to Qt: https://bugreports.qt.io/browse/QTBUG-97592
Comment 1 David Edmundson 2021-10-18 15:47:46 UTC 
I don't have context loss support in QtWayland yet, I'll comment on the upstream bug.
Comment 2 David Edmundson 2021-10-18 15:49:52 UTC 
kwin is also not reloading, but that's not fixable whilst we're using EGLStreams.
