A small update: I managed to rebuild the xserver-xorg-core package with
the patch applied, but the leak persists. So while it manifests the same
way and can be triggered by the same application, my problem seems to
have a different cause.
On a second thought, it makes sense: if I understand it correctly, XAA,
EXA, UXA etc. were replaced by Glamor in recent years. And from the Xorg
log it seems that that's what my laptop uses (Intel HD 5500), so I
should not experience any issues coming from the EXA code, right?
I'm not very experienced with Valgrind, but I'll send an update if I
manage to set it up and find anything of interest.

P.S. I had no clue about this transition to Glamor; Debian now generally
works well out of the box, so I'm not learning about new stuff by
constantly fixing stuff. :))
