 I would say it is probably a window manager issue.
 You can try to compile WindowMaker without dock, etc.
 Besides that, metacity seems to work fine to some degree with GNUstep.
 Azalea in Etoile is ported from OpenBox3 and is designed to work
better with GNUstep,
 but it is a work-in-progress.
 Since it is written in ObjC and relatively small,
 maybe you can customize it for you need.

 I think the root of problem is that EWMH only support 3 window level:
 above, normal, below (and other special level, like screensaver, desktop...).
 GNUstep need arbitrary window level.
 So if the window manager does not support it, it may be behave well.
