hi! thanks very much for your help.
the krita segfault still happens with all latest updates, including the most recent kernel 5.9.0-5-amd64
krita crashes at open. when i select the krita program from the menu nothing happens at all.
when i run like this:
$ krita
Segmentation fault
that's what happens....
i'm using lxqt
i'm using xorg as far as i know. haven't installed wayland deliberately
=======================
here's output from dpkg regarding wayland and xorg:
