That's glamor (in glamor_create_composite_fs() function), please file an
issue in gitlab [1] and attach the relevant logs
("/home/lombard/.local/share/xorg/Xorg.0.log").
I suspect this is with the latest xserver 21.1? I wonder if commit
a9552868 [2] could possibly be related, maybe try with xserver 1.20 to see
if it has the same issue?
Meanwhile, as a workaround, you may want to disable glamor in your
xorg.conf, it will be slower but it shouldn't crash.
