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.
