The issue

When I leave my laptop idle and let it lock itself, sometimes upon unlocking it, I encounter an issue where the screen constantly flashes white. Occasionally, if I stop moving the mouse, the screen returns to a mostly normal state. However, as soon as I attempt to type or perform any action, the rapid white flashing resumes.

I can still move things around on my PC and open new windows, but the laptop becomes basically unusable until I either switch to a tty to kill Hyprland and run it again, or I reboot.

I tried recording or taking a screenshot from the built in tools, but the white flashes are not visible there.

I haven't really changed anything in the config, just added some extra keybindings, changed the keyboard layout and touchpad settings, and changed the date format in AGS. Damage blink is off, as is the default. Damage tracking is on, as is suggested. However, I'm thinking maybe this is a shader issue so I just turned it off to see if that helps.

This is on a Framework 13 with a Ryzen 5 7640U.

It happened again and I was able to get a video of the issue. I noticed that damage tracking was back on again, maybe after I rebooted. How could I make that persistent? Could that help with this issue

by default no shader is applied
but to make damage tracking setting persistent you gotta edit the hyprland config
in ~/.config/hypr/custom/general.conf add the following

debug { 
    damage_tracking = 0
}

Thanks for the response. So if no shader is applied by default, do you have any ideas on what could be causing this? Or any way I could get logs for when this happens again.

no clue
maybe your gpu doesn't like hyprland
