I think I'm having the same issue

I am running TPM+FDE on Ubuntu 24.04. I tried to apply the workaround suggested with following command:
snap set system system.kernel.dangerous-cmdline-append="i915.enable_dc=0 intel_idle.max_cstate=2"

But I'm still seeing the same after a reboot. In my case, I have my laptop screen and external monitor in extend mode. The "flickering" is occurring only on the laptop screen (which is NOT set as the primary).

As others have described, mouse position seems to be a trigger for this, but not always in the same position.
