This used to occur sporadically for me (~6–12 months ago), then mysteriously
stopped (or became very rare), but then mysteriously started again about ~½ an
hour ago, after a reboot and an upgrade of the nVidia drivers (→
525.53_k6.0.8_1-16.3), fcitx (→5.0.20-1.1), and Qt6 (→6.4.1-1.1) from openSUSE
Tumbleweed. It's now happening pretty consistently (there are a lot of pending
notifications on Steam, all of which successfully display, then one of the
other steam windows will 'freeze'). One notification doesn't seem like it's
enough to knock it over (unless it's badly timed), but I'd wager that lots of
moving/resizing windows probably does…

This has only occurred with nVidia for me, and I think was helped last time by
an upgrade (or hack to fix threading bugs) of libnvidia-egl-wayland. I'm
currently running version 1.1.11, which should have all of the
previously-useful fixes. (I had assumed we were hitting this issue:
https://github.com/NVIDIA/egl-wayland/pull/53 )

Stacktrace from steam while it's frozen (only putting the active thread: the
others didn't seem hugely useful. It's all in X11/the nVidia driver):
