It didn't do anything for the shaking video problem. <https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1958191> looks like it might be similar to your "shaking". It's worth trying its cmdline options to see if either or both together have a useful impact:
i915.enable_dc=0 intel_idle.max_cstate=2
I've seen these suggested elsewhere, but never needed either myself. That bug resulted in this upstream bug that is still open: <https://gitlab.freedesktop.org/drm/intel/-/issues/5569>
Those bugs refer to kernel 5.15, which is nominally different, and modestly newer, than 15.5's 5.14. intel_idle.max_cstate=4 is at least one other suggestion in the newer bug. Others: intel_idle.max_cstate=3 i915.enable_psr=0 intel_iommu=on intel_iommu=off
If none of these help with "shaking", I suggest a bug be reported: <https://en.opensuse.org/openSUSE:Submitting_bug_reports> <https://bugzilla.opensuse.org/enter_bug.cgi?product=openSUSE%20Distribution>
I'll have to look into that. What kernel is in 15.4? I didn't notice this problem there.
