--- Comment #6 from Jakob Petsovits <jpe...@petsovits.com> ---
I hit this again. The code changed a bit since last time, but the assertion and
n_datas vs. planeCount values are similar. Let's add some extra info from my
new stack trace.

So far, so similar. I'm noticing that the pipewire code locations are also
included this time (Arch package: pipewire 1:1.0.5-1).
Pressing on.

The coredump will probably stick around for a few more days, I can post more
info if you tell me what to look for.
