Can somebody with a reasonably modern kernel version confirm this?

Dear Maintainer,

GeForce Graphics Card ASUS EN7300GT SILENT / HTD / 256M

Debian 11.6.0 64 installs:

Source: mesa  24 packets  v.20.3.5-1
Source: libglvnd  13 packets  v.1.3.2-1
Source: 9.0.2-1.1: libglu  2 packets  v.9.0.1-1

With this version of packages, any version of mupdf is compiled from source texts (from git too) and works fine. And the binary package mupdf 1.21.1+dd1-1 is installed and works fine.

But if you install:

Source: mesa  24 packets  22.3.1-1
Source: libglvnd  14 packets  v.1.5.0-1
Source: libglu  2 packets  v.9.0.2-1.1

then when mupdf-gl is started, the message "Error segmentation" is displayed and its execution is terminated. This happens with both the Linux kernel 5.10.20 and 6.0.0.6.

I happen to use an nVidia card with nouveau driver as well and have massive problems with OpenGL with all sort of
application. So this is probably a driver-related issue. You should switch to use the mupdf binary instead.
