In general, please keep asking [email protected]
There're four possible causes:
1) the window is tagged "override_redirect" (not managed by the WM, thus not
put into a managed stack, but simply on top of everything)
2) the rightclick menu is NOT tagged "override_redirect" and considered below
by the WindowManager
3) There is no WM (thus all windows are considered "override_redirect" and new
one will simply open on top of everything unless the client restacks them
itself, ie. plays WM)
4) there's no compositor, the video uses an overlay technique (xv/vdpau) and th
popups color matches the color key of the overlay (the GPU will replace the
matching color in the matching region with the video content, bypassing X11)
A window manager would be sth. like fvwm, kwin, compiz, metacity, lwm, e16,
openbox, mutter and a dozen other variants - desktop environments like gnome,
kde, xfce, lxde usually run a WM, but if you just start an X11 display server,
there won't be one - and "something else" (your client, i assume) has to
control the stacking order of all relevant client windows.
Cheers,
Thomas
