The main program blocks when the window is dragged or resized.

As you can see from the title, this issue seems to be Windows only!It's very annoying and I couldn't find a solution anywhere else

Unfortunately, there’s nothing we can do about it for now. This is an SDL limitation. If I remember correctly, SDL3 will have an opt-in way of fixing it, but it’s not released yet, and it’ll probably take us some time to adopt it after the release (thanks @Starbuck5 for championing the SDL3-compat efforts so far). I’ll leave this issue open for now because it’s a legitimate issue, just not one we can fix right now. I’ll look later when I’m back at my desk to see if this is a duplicate of another open issue

There's a closed issue with more information:

I've noticed that since the blocking is basically equivalent to an arbitrarily large lag spike (since time-related functions like pygame.time.get_ticks() aren't affected), there can be some pretty bad effects if you use certain types of game loops.
It messes up the delta time, which leads to either more freezing or physics issues, if your program depends on the delta time.

It messes up the delta time, which leads to either more freezing or physics issues, if your program depends on the delta time.

A common workaround for this is to cap your delta time. If your frame time exceeds that cap, then artificially set it to the cap
