Slightly off-topic, but hopefully related enough:
I've been affected by [freedesktop #3569][0], which also is related to
older eDP panels and which started with the 5.11.0-22 as in the original
report here. (Instead of "wobbly" graphics, I simply get no graphics
whatsoever.)
Happy to report that
I've just installed 5.11.0-38-generic from Hirsute-proposed and I can
confirm that it works. I've also changed the tag, like the bot asked. I
hope it's OK.

OK, linux-modules was installed but linux-modules-extra was not. I

back. I removed it, rebooted, and still the distortion was there, but
the desktop and network was working. I cannot repeat what happened the
first time I booted

Installed linux-image-5.11.0-34-generic from proposed. It seems to fix
the issue with graphics distortion from the decryption prompt onwards.
Unfortunately it doesn't work very well after that. There is a message
on the screen about something having failed and automatic reporting
being enabled.
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
