Hi all,
I have some weird graphic glitches, but only on KDE and Eos.
I dont know why and how to fix it.
Video of it is here : https://we.tl/t-ErX9MTM7S4
any help is appreciated 
What is your hardware again? Do you have Intel Iris and Nvidia?

Holy crap, I’m also having these issues, but only on AMD Radeon dGPUs. On the other hand, these issue do appear on both GNOME 44 and KDE Plasma 5.27. On Plasma, if I change anything with the desktop or go full-screen in GNOME, the screen goes white and the only way to fix it is to either hard reset (in KDE Plasma) or exit full-screen (in both KDE Plasma in games and GNOME in any full screen mode, including with Totem / GNOME Videos).
Edit 2: Ocaassionaly, the laptop will do what the OP’s video showed; it was 50/50 between becoming a seizure-inducing mess and forcing a warm reboot or going completely white and needed a hard reset.
I don’t know if it’s the AMD Mesa drivers, but this may need to be looked at, given I’ve been on the same install since the infamous GRUB bootloader issue.
I was literally just about to create a post just like this one, but I’ll save you guys the headache.
Edit: here is the results of running the same command as the original poster:

BTW, Brtza, is your laptop the Legion 7 2022?

Oh ya i forgot it’s AMD graphics. I don’t have any issues on mine normally with my AMD graphics on KDE. But, there are occasions where if i have the cursor sitting in the taskbar on some of the icons it can cause some flutters or graphic anomolies but it’s not the entire screen. What do have installed for amd beside using the amdgpu?

I dont know what I have installed. Everything is default
so I am not alone, hehe
I have Lenovo Ideapad 5 pro
Well most have to be installed. I gave the link for arch wiki. You can read up there about it. Not that you need them all but i installed them anyway and set up for hardware acceleration etc.
Edit: My KDE rarely has any issues but I have seen some small anomolies or glitches with the cursor sometime resting in the task bar on icons. It’s very minor and only happens rarely.

I checked that link before, but dont know what I need. so dont wnat to install something and screw it even more, hehe
My problem started with the Plasma 5.27 upgrade, but nothing seems to fix it. Considering a second partition with EndeavourOS is doing it with GNOME 44, it may be something with Lenovo’s AMD GPU firmware.
Either way, I’m probably going to get a Tuxedo Stellaris 16 laptop and stick EndeavourOS on it. Yeah, it has Nvidia and all of their driver BS, but that would also allow me to use DLSS and CUDA, neither of which are possible on AMD GPUs.
You wouldn’t mess anything up installing any of those packages i don’t think but then again unless you need them ? I tend to just install whatever i think would be of a benefit if i ever needed it.
