Tons of different PySDL2 crashes when tabbing in/out of application during loading or right after it finished

See original GitHub issue

Testing around, my PySDL2 app crashed (I think it was when I tabbed out with the home button):

Well, it’s most likely me doing something wrong. But it would be useful to document this somewhere, the minimum events that need to be handled through SDL2 to avoid crashes like this. (Because it’s not really comparable on the desktop, where the program doesn’t crash due to this.) Anyway, I’ll close the issue for now

Ok, part of those crashes were because I got a window close event and didn’t handle it. Now that I do and free all resources of the window (along with SDL_DestroyWindow) once that happens, I am seeing this once I tab out and tab back in (crash happens when regaining focus / tabbing back in):

It works fine on the desktop by the way, where I can close the window, see the window close properly processed and nothing crashes.

Also, how is this supposed to work anyway? When I tab out and the window closes, now the app has no window - how will it ever open one when gaining focus again? After all, I didn’t want to close it, I was forced to by python-for-android triggering a close event, so what is it supposed to show anyway once it regains focus…?
