This is related to kernel 6.5 and happens for me on Ryzen 5 3500U on Mantic Minotaur.
It is fixed in kernel 6.5.6, as described here: https://gitlab.freedesktop.org/drm/amd/-/issues/2830
I first saw this on Fedora with kernel 6.5.5 (it was not present on kernel 6.4) and can confirm kernel 6.5.6 fixes it.
I really hope Mantic is not released with the kernel it has now.
