So half a year later and I was still getting these crashes. I found the 
possible issue. More and more people started having the same crashes as 
different distros were updating their X11 stuff. It seems the issue is this:

   https://gitlab.freedesktop.org/xorg/xserver/-/issues/1261

A patch was merged in xorg upstream about 4 months ago:

   https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/865

Downloadable diff:

   https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/865.diff

This patch is not carried in portage. I copied it to 
/etc/portage/patches/x11-base/xorg-server/ and rebuilt xorg-server three 
days ago, and I haven't had any more crashes.

Fingers crossed...
