An Intel:
0000:00:02.0 VGA compatible controller: Intel Corporation Raptor Lake-P [Iris Xe Graphics] (rev 04)

But I don't understand how you folks can't reproduce. It triggers an
assertion failure, it's not random.

To try to reproduce, first select a normal, approximately square zone
and copy it. Verify that you see it appear at the top left of the
Patterns dock:

https://www.colino.net/tmp/normal.png - here, the computer I just copied
is in the Patterns, highlighted in red.

Then try to select something REALLY flat (1px high), as in
https://www.colino.net/tmp/not_good.png (the selection is also
highlighted in red).

Copy it. My Gimp 2.10.36-3ubuntu0.24.04.1 crashes with an assertion
failure, showing the following in the terminal:

```
colin:a2tools/src/glider$ gimp assets/levels/level_a.xcf 
using gegl copy
using gegl copy
gimp: Gimp-Core-CRITICAL: gimp_temp_buf_new: assertion 'width > 0 && height > 0 && bpp > 0' failed
gimp: fatal error: Segmentation fault

warning: could not find '.gnu_debugaltlink' file for /usr/bin/gimp-2.10

warning: could not find '.gnu_debugaltlink' file for /lib/x86_64-linux-
gnu/libgimpwidgets-2.0.so.0

warning: could not find '.gnu_debugaltlink' file for /lib/x86_64-linux-gnu/libgdk-x11-2.0.so.0
```

The important line is: Gimp-Core-CRITICAL: gimp_temp_buf_new: assertion
'width > 0 && height > 0 && bpp > 0' failed

Thanks for trying to help :)
