Since the kernel 5.9.1 update i have graphical glitches after cold booting my laptop. Suspending and waking it up again fixes the problems. I already tried disabling the amdgpu kernel module which solves the graphical glitches, but i obviously can’t use my dedicated graphics card which is a must.

5.4 was released a couple of years now (November 2019), so can you be a little more precise about the kernel series and versions you have tried?
Sorry for that. I have now looked in the pacman logs and found out that linux 5.9.1 introduced the bug. With kernel version 5.8.14 everything worked.
Have you tried removing xf86-video-intel?
Removing xf86-video-intel fixed my issue. Thank you for your help!
