Prevent SDL Window blocking main thread during battle

[vkedwardli]

During battle, make the window not resizable in macOS, and not resizable + draggable in Windows.

Long standing issue: libsdl-org/SDL#1059

one person decides to drag or resize their window, and the whole session dies, pissing off all of the players trying to play

One player (not even the host) was dragging their window in a match I had and everyone was confused as to why everyone was suddenly lagging

This makes good players inconvenient, so I want a better way.

Locking it only after if the event happens for more than 10 times or 20 times?

This does not solve the problem and it would be difficult to follow the code because changes in multiple places.

Let's take a more consistent solution. ex:

• Render while dragging (I know this is difficult with SDL2)
• Allow moving, maximizing, resizing, and minimizing the window without title bar

[vkedwardli]

Since we are not solving the inconvenience caused by moving windows, but the bad intentional caused by players by abusing this feature. Even if we solved the Windows SDL drag window blocking, bad player can still block the game using Resizing method.

So it won’t be solvable?

Like disconnection, it should be viewed as an unavoidable disturbance.
How about recording window drag and resize during a battle and sending with matching report?

Can you test the patch in the issue?
