This is now fixed for intel gpu based machines.
XServer issue: https://gitlab.freedesktop.org/xorg/xserver/-/issues/1183
Merge request that has fixed that on Xorg Xserver 1.20 branch (server-1.20-branch):
https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/686
Please incorporate that fix to Ubuntu 1.20

To sum up fix is solving extreamly slow refresh rate(1FPS) when laptop lid is closed or DisplayLink display is the only one. This fixes laptops with intel cpu.
For amd,nvidia gpus fix is not ready yet.
