Process crash upon DPMS on

[a-priestley]

This doesn't seem to happen every time, but the longer my displays are off, the more likely it is that this will happen when they turn back on. I'm using two displays with different resolutions and refresh rates.

Trace:

Process 3844226 (swaylock) of user 1000 dumped core.

░░ Subject: Process 3844226 (swaylock) dumped core

░░ Process 3844226 (swaylock) crashed and dumped core.
░░ 
░░ This usually indicates a programming error in the crashing program and
░░ should be reported to its vendor as a bug.

It happens with both this fork, and with the upstream swaylock-effects, but not with swaylock.

After a system update today, this seems to have been resolved. however effects do not work properly on the secondary display after resume (white background).

This has started happening to me... NixOS unstable (currently at 897876e4c484f1e8f92009fd11b7d988a121a4e7, kernel version 6.3.1, swaylock version 1.6.11.

[jflanglois]

I don't have good evidence for this yet, but it might be related to the grace period. I'm trying things out with no grace period and it seems to be working fine so far. It could be that there's a bug in the time calculation? The lock screen does seem to disappear on input when it malfunctions.

Could this be related to the hyprland discussion here? hyprwm/Hyprland#4134
