Please describe your issue in as much detail as possible:

When I connect to my gaming PC via Steam Link I get a distorted image on my TV.
On the gaming PC the Steam UI stays usable for about 10 seconds, then the screen turns black and Steam crashes.

The dump file created somehow doesn't get uploaded (as seen in the crash log) so I'm including it here for debugging purposes:
crash_20230225222732_47.dmp.zip
steam-stdout-crash.log

Steps for reproducing this issue:

1. Connect to Steam via Steam Link
2. Wait about 10 seconds
3. Have a black screeen

Hello @DaedalusHyperboreus, the minidump you attached is a SIGSEGV in libX11.so.6.4.0. This is a distro issue and needs to be evaluated by a ChimeraOS dev.

Out of mild curiosity, what 32 bit and 64 bit versions of libX11 is being packaged by that distro? We're already aware of some regressions in libX11 1.8.2 and 1.8.3 which effectively makes those point releases defective.

[DaedalusHyperboreus]

The versions of libX11 packaged in ChimeraOS 39 are as follows:
extra/libx11 1.8.4-1 [installed]
X11 client-side library
multilib/lib32-libx11 1.8.3-1 [installed]
X11 client-side library (32-bit)

[DaedalusHyperboreus]

I just upgraded lib32-x11 to 1.8.4 to see if it would make a difference.
The behavior is practically the same, however.

Just in case they're useful, here are the dumps that got created:
assert_20230301125726_120.dmp.zip
crash_20230301125727_121.dmp.zip
steam-stdout-crash.log

I managed to downgrade libX11 to 1.8:
extra/libx11 1.8.4-1 [installed: 1.8-1]
X11 client-side library
multilib/lib32-libx11 1.8.3-1 [installed: 1.8.1-1]
X11 client-side library (32-bit)

Steam still crashes when Remote Play is attempted, however:

i'm currently experiencing similar behavior trying to use my steam deck as a host, using steam os 3.4.8 (build 20230508.1). steam client version on the deck is 1689034492, from the stable branch, built july 10, if that helps.

seemingly at random (it works sometimes, but usually doesn't) connecting to the deck from another system causes the deck to spontaneously reboot. i've used both steam for linux (on both ubuntu and debian based systems) and the android steam link app.

presumably related, i seem to consistently have my deck reboot when i attempt to invite someone on windows to watch my game.

are there specific logs that would be useful for diagnosing this? i'm not quite certain where to look.
