This is a low crash. Looks like the code failed to do a memory move operation, however, I checked a few crash reports and they all seemed to have a decent amount of memory left.

We're mid-update for libwebrtc, I'll call this a p3 until we see if the update helps since it is low volume.

Severity: -- → S3
Priority: -- → P3

This is probably related to
gsettings set org.gnome.mutter experimental-features "['dma-buf-screen-sharing']"
