No, I don't usually use GTK3. So I looked for anything that uses GTK3
on my system and that was gcr-viewer. Also, since the XFlush() worked
for me I suspect that there is some kind of race condition involved.
I wasn't too confident that patch would help you too.

My system at home usually also behaves differently from my work machine.
I'll try things at home and maybe I find another workaround.

Hmm, AFAIK dwm doesn't unmap windows but rather moves windows in and
out of view when switching tags. On the other hand VisibilityNotifies
might still play a role in this, but I wouldn't bet on it. I'll keep
it in mind though.
