I upgraded F39 to F40, KDE spin, and experienced no other issue than that since the upgrade inside a (Remmina) RDP session, often - but not always - some rectangular regions of the screen start flickering. This most notably happens when (in the RDP session on a Windows server) I switch between VSCode and the Git shell. Some of the regions can be small, others can be larger; it’s random.
This never happened in F39 (so could be a Wayland thing).
When I put something on top of the flickering region of the screen or something similar to it, the flicker goes away. I can’t even make a video of it, because immediately when I start recording, the flicker goes away.
FTR, this didn’t help: Flickering on Fedora 40 NVIDIA driver 550.78 - #3 by msmafra. (Also, the flicker doesn’t look like in that movie.)

I’m not sure what other information is relevant.
Does anyone know a solution for this?
