screen sometimes blinking

[dom21121]

My screen sometimes starts flashing strongly. I move the mouse cursor, it stops. I put the cursor back in its place, it starts again.
I notice this with Firefox because I use it a lot, I don't know if this happens with other software.
I'm under wayland (xwayland?)

A video.

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

Please try adding a kernel parameter:

  i915.enable_psr=0

[dom21121 (dom21121)]

thank you for your reply. I applied the settings in grub. I will let you
know if I notice the flashing again.

Sorry but after applying the setting the screen flashing continues...

Hello it's happening also to me, ASPIRE ES1-172+36XH, i3-6006u, Intel HD Graphics 520

[Daniel van Vugt (vanvugt)]

After editing /etc/default/grub, please also run:

  sudo update-grub

and then reboot.

[dom21121 (dom21121)]

Already done ! 🙁

Please try adding this to /etc/environment:

  MUTTER_DEBUG_FORCE_KMS_MODE=simple

and then reboot.

[dom21121 (dom21121)]

no effect...

Sounds like we're correct in assigning this to the kernel then.

Next please try some older kernels to identify when the problem started:
https://kernel.ubuntu.com/mainline/?C=M;O=D

[dom21121 (dom21121)]

I undo the changes in /etc/default/grub and etc/environment (?)

I'm trying different kernels and will get back to you as soon as I find
the right one.

I'm not sure you even need to undo the changes in /etc/default/grub and etc/environment if the bug is still happening. But sure...

[dom21121 (dom21121)]

kernel 6.7.7 -> BUG

kernel 6.7.6 -> I've been using my laptop for a while and still NO
flashing...🙂

( -> Without  changes in /etc/default/grub and in etc/environment)
