Has for me the side effect that sometimes I have to press ctrl-alt-2 twice. Showing window first time works. Hiding the window works too. Showing it the second time needs the double keypress. Added fprintfs to figure why [1]. Reason for that seems to be a suspious SDL_WINDOWEVENT_SHOWN event from SDL, so qemu thinks the window is visible even though it actually is hidden. Have a slightly older SDL version (2.0.3). Do you see that effect with 2.0.6 too? cheers, Gerd https://www.kraxel.org/cgit/qemu/commit/?h=testing/sdl&id=8235bfb66e7c82870ff1b1f47bdaaf4f522c5444
