I've been running this way ever since you've asked me, but that stack trace was the only one I was able to trigger, though improper rendering happened a lot.
I am positive that when I caught that trace there were no errors in dmesg.

Now, 2.21.4 is out and I will continue trying to catch something, though
since it happens only in firefox maybe there is issue somewhere else?
What versions of firefox, cairo and gtk do you have?

Also I've noticed this message in .xsession-errors whenever I move previews in Firefox:

(firefox:3574): GdkPixbuf-CRITICAL **: gdk_pixbuf_new: assertion `width > 0' failed

This happens both with FORCE_FULL_SYNC 0 and 1.
