Actually, the XorgLog.txt shows more definite problems:
[181434.889] (WW) modeset(0): flip queue failed: Device or resource busy
[181434.889] (WW) modeset(0): Page flip failed: Device or resource busy
[181434.889] (EE) modeset(0): present flip failed
[181434.989] (WW) modeset(0): flip queue
Or it could be the framebuffer compression or other power saving things.
Since the last relevant kernel message is:
[180893.945295] [drm] Reducing the compressed framebuffer size. This may
lead to less power savings than a non-reduced-size. Try to increase
stolen memory size if available in BIOS.
This looks like another atomic mode setting problem. To test this
theory, please try 'Ubuntu on Wayland' and tell us if it avoids the
jitter.
If so, then this Xorg fix from Intel is probably what we want to keep an eye on:

btw, as record. After reboot of this issue. I also updated BIOS by fwupd

from the apt history log, it looks not something fishy as well.
BTW, the only package I installed these 2 days is multipass snap package.
I use it to run a bionc VM to test TLP behavior.
