Hi Jonathan,

I'm also using Wayland on 13.2, but I believe an older graphics card. I'm n=
ot having the same issue.

I do, however, have some weird OOM-like behavior sporadically with Firefox.=
 System will lock up pretty hard for a while, kill something (usually Firef=
ox), and tends to say that the thread timed out waiting for a page. I guess=
 it's probably not the same thing, but thought I'd mention it.

-Henrich
