sdl 2.0.4 currently has a bug which causes our UI shortcuts to fire
rapidly in succession:
https://bugzilla.libsdl.org/show_bug.cgi?id=3287
It's a toss up whether ctrl+alt+f or ctrl+alt+2 will fire an
odd or even number of times, thus determining whether the action
succeeds or fails.
Opening monitor/serial windows is doubly broken, since it will often
lock the UI trying to grab the pointer:
0x00007fffef3720a5 in SDL_Delay_REAL () at /lib64/libSDL2-2.0.so.0
0x00007fffef3688ba in X11_SetWindowGrab () at /lib64/libSDL2-2.0.so.0

0x00007fffef2eeab5 in SDL_WaitEventTimeout_REAL () at /lib64/libSDL2-2.0.so.0
0x000055555597eed0 in sdl2_poll_events (scon=0x55555876f928) at ui/sdl2.c:593
We can work around that hang by ungrabbing the pointer before launching
a new window. This roughly matches what our sdl1 code does
