You can try the fix from the thread below that may improve the situation for you:

F41 The screen flickers and shows visual artifacts when I type or scroll

You won’t have to download external drivers, as the AMD drivers for your GPU are included with the kernel. You may be able to get rid of the artifacts by adding this boot parameter to the kernel: amdgpu.dcdebugmask=0x10 You can add it to the config file /etc/default/grub like this: GRUB_CMDLINE_LINUX="rhgb quiet amdgpu.dcdebugmask=0x10" Then regenerate grub: $ sudo grub2-mkconfig -o /boot/grub2/grub.cfg After rebooting the artifacts may not occur anymore.
