kernel version newer than lts, screen artifacts when integrated graphics isn't under load.

I'm not sure where to bring kernel driver issues for amd integrated graphics. When I switch the kernel to linux-lts, the problem goes away entirely. I initially noticed this issue on fedora but now I'm on archlinux.

Anytime there's a blur, hardware accelerated browser, or an interface that uses the gpu it causes artifact every update. If the updates are too frequent, there's something like vkcube running, or something like hardware video decoding the artifacts go away. If I switch to xorg there are no artifacts. The artifacts persist across gnome and kde but go away entirely when hooked up to a 4k 120hz monitor via usb4 (thunderbolt).

The artifacts often happen around the content that's updating or a horizontal strip across the blurred surface about the same height of the updated content.
