Hi,

When I toggle SDL2 fullscreen <F11>, the mouse cursor gets repositioned
because of the different screen sizes. The mouse cursor doesn't always
get repositioned in a manner that I understand... probably in an
incorrect manner. This probably causes the host computer to change
'window focus' when changing the screen sizes; giving bogus coordinates
and wreaking havoc.

Here is a possible clue that makes a slight difference:

(hatari/src/main.c)

/**
 * Set mouse pointer to new coordinates and set flag to ignore the mouse event
 * that is generated by SDL_WarpMouse().
 */
void Main_WarpMouse(int x, int y)
{
#if WITH_SDL2
	SDL_WarpMouseInWindow(sdlWindow, x, y);
#else
	SDL_WarpMouse(x, y);
	bIgnoreNextMouseMotion = true;
#endif
//	bIgnoreNextMouseMotion = true;  ^moved up^  **NOTICE HERE**

}

Hopefully this info will be helpful. Note that this does not
solve the problem.
