Hi,
The following was noticed on Hatari(old core), SDL2, CentOS6
(The laptop where Hatari SDL2 works great).

The good
1) run hatari and position mouse in approximately center of hatari screen
2) press F11 and notice that mouse is correctly in the same relative spot
3) toggle F11 a few times and note that all works properly as expected.

The bad
4) run hatari and position mouse in Top Left of hatari screen.
5) press F11 and notice that mouse is incorrectly GONE. (repeat a few times)

The ugly
6) run hatari and note that the hatari window is centered on the desktop.
7) move the hatari window.
8) press F11 and note that hatari is full screen.
9) press F11 and note that the hatari window is !!! centered on the desktop.
10) repeat (7) to (9) to note that the hatari window is erroneously re-centered.

Thus there is a problem with the mouse and the window in SDL2
(this problem may manifest itself differently on different systems).
