Description Robert Vollmert 2010-07-02 04:36:40 UTC 
I ran into trouble with an SDL application using SDL_RESIZABLE with the xmonad window manager, which treats the SDL window as a floating window. It does so because the window has a WM_TRANSIENT_FOR property (with invalid value 0x0).

This appears to be because of the call to XSetTransientForHint(SDL_Display, WMwindow, None). That seems to be an invalid use of XSetTransientForHint; I think gdb showed it returned an error. Maybe there's also a bug in libx11, in that XSetTransientForHint shouldn't actually set the property if an invalid parent window id is passed?

At any rate, removing that call solved the problem.

This was with current SDL-1.2 (HG) on Arch Linux, xmonad from darcs, libx11 1.3.4.
