Weird mouse cursor lag problem.

When I move my mouse (Logitech G502 X Wired) the cursor moves very laggy/in low fps, this doesn't happens when using touchpad, moving mouse cursor also makes the cpu spike to 7% from 1% (again, doesn't happens when I use touchpad), I have noticed that if I have steam open this problem gets fixed but if I close steam or minimize it to tray, it starts to happen again (this problem was still happenning before I installed steam or anything). I installed Arch today on my laptop with archinstall command.

DE: KDE Plasma 6.2.4
Session: X11 (happens on wayland too)
Kernel: 6.12.4-arch1-1 (64-bit)

Laptop name: ASUS TUF Gaming A16 FA617NSR
CPU: AMD Ryzen 7 7435HS
GPU: AMD Radeon RX 7600S

this didnt change anything at all, still having the same problems, also i noticed that this bug doesn't happen (mostly) on wayland. this bug still happens on sddm login screen (iirc it uses wayland) and xorg.
i also noticed that on black mesa there are a lot of visual bugs that its mostly unplayable and on half life 1 just fastly sliding settings is enough to cause major lag.

Re: Weird mouse cursor lag problem.

You need to add amdgpu.dcdebugmask=0x200 as a kernel parameter.

I didn't saw this fix but after trying it it was sorta working but not completely. Issue was kinda fixed on wayland but not at all on xorg.

If you're having weird pixel bug on the top 20 pixel of your monitor and moving your cursor makes everything lag, go to /etc/default and edit grub file, add amdgpu.dcdebugmask=0x10 inside of GRUB_CMDLINE_LINUX_DEFAULT=""

amdgpu.dcdebugmask=0x200 doesn't work very well but 0x10 works perfectly. the issue is related to power saving features. I edited the arch wiki page for asus laptops but I guess it's waiting approval (new changes are only visible for me).
