Drat, looks like the new Fedora 42 got rid of SDL2 and replaced it with the
mingw64-sdl2-compat wrapper that uses SDL3 as the backend. I downgraded the CI
job to Fedora 41 now, I hope that should avoid the problem for a while.
In the long run, after the next release of Hatari, I guess I'll finally have
a closer look at Andreas' patch to update Hatari to SDL3...
FWIW, I have been using sdl2-compat wrapper for a while now in both Aranym and Hatari. It has become much better now, virtually I can't tell the difference against true SDL2 anymore.
