Bug 1911130

From what I've been able to read in other places, this problem appears to be with mesa 10.3.x. Pidgin isn't the only piece of software that broke with mesa 10.3.x. Just searching for the error "lavapipe is not a conformant vulkan implementation" shows there are others. The only solution I can find is to use an older version of mesa (10.2.x or older) until the developers of mesa fix the problem. Not even the most recent version of mesa (10.3.2) appears to fix this...

Thanks for narrowing this down, you just saved me some time this morning digging through
exactly RPMs had gone bad (I've got a little script that converts the output of 'ldd' into
relevant RPM names, but that was ppointing at gstreamer1 and not Mesa because gstreamer1
loads Mesa on the fly).

Confirming that Mesa 20.2.3-2 from Nov 30 works, but 20.3.0~rc2-1 from Dec 1 is duff.
20.3.2-1 just landed in koji this morning (Jan 1), but still busted).

Moving this from 'pidgin' to 'mesa'.

The backtrace shows the crash happening in /lib64/libgstvulkan-1.0.so.0 , so that's the prime suspect.

Backleveling Mesa makes things work.  So it's unclear whether Mesa broke something, or if GStreamer is doing something wonky that used to be allowed but now causes problems. Mesa's behavior has obviously changed in some manner, but somebody more clued than me is going to have to figure out what's different, and whether it's GStreamer or Mesa that needs fixing.

The issue seems to be with gstreamer1-plugins-bad-free-1.20.3-1.fc36.x86_64.

Disabling libgstvulkan.so by deleting or moving away this file "solves" the issue with pidgin:

$ sudo mv /usr/lib64/gstreamer-1.0/libgstvulkan.so{,.bad}
