gamescope crashing after waking up from suspend since v44

[mad526]

Issue

Since upgrading to 44, ChimeraOS wakes up to the 'verifying installation' screen after being suspended for more than 1 minute instead of Steam, i.e. Steam seems to crash and restart. This was not the case on 43-1.

According to dmesg, gamescope-xwm is segfaulting and presumably causing this behavior. [ 4156.775303] gamescope-xwm[874]: segfault at dc ip 0000565431f4e458 sp 00007f9d7a7fb428 error 4 in gamescope[565431f3a000+9d000] likely on CPU 11 (core 3, socket 0)

I get the same if I just shutdown the TV the PC is attached to for about one minute. Steam restarts when I turn on the TV again.

Issue is still present in 44-1, but I found a workaround that works most of the time: If I turn on my TV and AVR and then wait at least 5 seconds before waking up ChimeraOS from suspend it usually does not crash. Possibly the whole thing is related to the HDMI handshake?

I tested this again on 45_5340f50 and still happens.

Also, I don't even need suspend to make it happen. If I hold the shutdown button on my TV remote, so that it does not simply sleep but shuts down completely, when I turn on the TV gamescope crashes as above.

If it can help, these are the lines that appear in ~/.gamescope-stdout.log as I shut down the TV and turn it on again:

If it helps, I see a similar issue to @rzippo with gamescope+steam big picture in a different implementation (HoloISO with latest updates as of 2023-12-04). Perhaps this can help narrow down to similarities between the two implementations of "super easy boot to Gamescope" :)

When I turn on the TV after it has been powered off, steam session restarts and I see the following in dmesg:

gamescope-xwm[3572]: segfault at dc ip 0000562a727a63a8 sp 00007f1b23ffe468 error 4 in gamescope[562a72792000+9c000] likely on CPU 7 (core 1, socket 0)

HoloISO must use a different gamescope config / launch params as I don't have a ~/.gamescope-stdout or a file named that anywhere in the user's home dir - I'll try to see if it sinks Gamescope stdout somewhere and report back.

Can anyone test again using the latest stable build of ChimeraOS 45?

I run the same test on 45-1_ea2fd2f, still happens.
