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 (eduActiv8 Dev)
