Dear Maintainer,
when I run pysiogame in console I get:

pygame 2.1.2 (SDL 2.24.1, Python 3.10.8)
Hello .....
Traceback
file "/usr/share/games/pysiogame/eduactiv8.py", line 659, in <module>
 main()
file "/usr/share/games/pysiogame/eduactiv8.py", line 649, in main
 app.run()
file "/usr/share/games/pysiogame/eduactiv8.py", line 408, in run
 self.create subsurfaces()
file "/usr/share/games/pysiogame/eduactiv8.py", line 131, in create_subsurfaces
 self.game_bg = self.screen.subsurface(self.sizer.game_bg_pos)
ValueError: subsurface rectangle outside surface area

After that pysiogame crashes immediatly.
Thanks.
PS
this is with Bookworm, with Bullseye pysiogame works fine.

Dear Gerard and Maintainers,

Thank you for reporting the issue and sorry for the late reply, I only just
realized a new bug was reported.

If I am not mistaken I have encountered this issue previously. The problem
is that the latest distros started using Python 3, Pygame 2+ and the latest
SDL 2+ which seems to draw windows differently. I ended up changing the way
the program's window gets resized at startup which I believe solved the
reported problem.

The latest source release (just published with the fix) is available on
GitHub at: https://github.com/imiolek-ireneusz/eduActiv8/releases

The upstream version also solves issues: #721829, #721830, #721899 and
#721852.

A hopefully working, but not the most up-to-date (yet) version is available
at:
https://software.opensuse.org/download.html?project=home%3Aimiolek-i&package=eduactiv8

FAO: Maintainers - just in case any of the configuration files here are of
any use:
https://build.opensuse.org/package/show/home:imiolek-i/eduActiv8

I would really appreciate if you could confirm the latest source code works
as expected, please.

Thanks,
Ireneusz Imiolek
