SDL_WINDOWID hack fails


has anyone experienced the problem that the YUV overlay gets its own
detached window despite setting SDL_WINDOWID? It works for me and
seemingly everyone else. However, one user of my application reported
that the overlay appears in secondary window. He uses SDL 1.2.9
with X11R7 on Fedora Core 5. I’ve verified that the environment
variable is correctly set to a non-zero window ID. The GUI uses Gtk+
1.2 and nobody else has reported such an issue before.–
