So don't try to set a window icon when we don't have any outputs. https://bugzilla.redhat.com/show_bug.cgi?id=1340931 --- ui/sdl2.c | 20 +++++++++++--------- 1 file changed, 11 insertions(+), 9 deletions(-) diff --git a/ui/sdl2.c b/ui/sdl2.c index 909038f..d0e0a41 100644 --- a/ui/sdl2.c +++ b/ui/sdl2.c @@ -812,16 +812,18 @@ void sdl_display_init(DisplayState *ds, int full_screen, int no_frame) register_displaychangelistener(&sdl2_console[i].dcl); } - /* Load a 32x32x4 image.
