I am getting flickering/tearing at login screen on wake up...anyway to fix this?

[automate-stuff]

I am getting some flickering(or should i say tearing?) when waking up...is there a way to fix it or is it how it is supposed to be:

sometimes it is worse than the video...sometimes the flickering/tearing happens to the desktop too when the desktop appears for the first time after login.
This doesn't happen when I wake-up/swipe/suspend/wakeup again ... there is no swipe screen in this case...any way to disable the swipe screen ?

after getting that video issue, glance at 'journalctl -b' output to know what is going on.

(hopes igpu 515 is not too old to support focal needs)
