Update 2026-08-26 — still reproducing after client/OS updates

This has not gone away. Steam Support did not reply. The crash is still a SIGSEGV in the main 32-bit process (ubuntu12_32/steam), including while idle with no game running.

What changed since this issue was opened

	2026-07-09 (original)	2026-08-26
Steam client buildid	`1782866176` (updater Jun 24)	`1785799196` (updater Aug 3)
Kernel	6.18.38_1	6.18.44_1
Mesa	26.1.3	26.1.6
Beta	No	No

Same machine otherwise: Void Linux steam-1.0.0.85_1, XFCE 4.20 / X11, AMD 3020e + Vega 3 (RADV RAVEN2). Still not OOM (idle crash RSS ~226 MiB, ~11 GiB free).

Frequency

console-linux.txt + previous log: 42 SIGSEGV in steam.sh from 2026-07-03 through 2026-08-26. Typical pattern: client starts normally, then dies on its own after minutes to a couple of hours. After the main process dies, steamwebhelper logs stalled cross-thread pipe (pipe is disconnected) — that looks like a follow-on, not the first fault.

Still fails with -cef-disable-gpu / steam --reset (from the original report). Happy to attach logs or a minidump if useful.

Possibly related: #13496 (same client 1785799196, random idle/startup segfaults on Ubuntu).
