The same code works fine when using non-fullscreen modes, or when using desktop fullscreen.
Unfortunately on multiple machines (one, eeepc with intel graphics chipset, two, desktop with ati 5800) and under XP,
using mingw,
SDL2 crashes when exiting fullscreen mode.
There’s no problems with the code, and neither of the machines have problems with (non-desktop) fullscreen games.
The code below is just some simple instantiation for demonstration purposes, no texture displays etc. In my real OO code with textures displayed, it does exactly the same thing. Changing the resolution size makes no difference.
The problem may be specific to mingw + SDL2,
or it may be specific to XP + SDL2. Or a combination.
