Screenshot of testsprite2 --fullscreen working badly.

On vmware, creating a 640x480 (or whatever) fullscreen window fails to work, even though the X server reports it supports a 640x480 resolution (see attached screenshot).

When running "./testsprite2 --fullscreen", it "changed resolution" (in vmware's case: resized the window on the host machine), but failed to put the SDL window in the right place. If I then hit ctrl-g to grab the mouse, or ctrl-r to toggle on relative mouse mode, it fixes itself.

Note that the window is rendering incorrectly (the sprites are _way_ too big; is this a matter of SDL_RenderSetLogicalSize() getting the wrong dimensions?). When grabbing the mouse fixes the window, this all starts rendering at the correct size.

--fullscreen-desktop works correctly in any case.

Default Ubuntu 17.04 install in the virtual machine.

This appears to be working correctly on real hardware with a real 640x480 resolution available, and _maybe_ this is a vmware bug, but since SDL can right itself here when grabbing the mouse, I'm wondering if there's some magic incantation we can do at the end of X11_CreateWindow() that will sync all this up, or some wait we have to do while the X server changes resolutions that we aren't doing, etc.

A quick test shows this has been broken all the way back to SDL-2.0.0, and since no one is complaining loudly, this probably isn't super-urgent.
