Package: xcompmgr
Version: 1.1.5-1
Hi!
I'm writing a program that uses the SHAPE extensions to give a window a
non-rectangular shape. This works up to the point where I try to modify
the shape at runtime. The attached example program creates a simple
window of 50x50 pixels. It then creates a moving square of 10x10 pixels
inside that window which is not part of the window, using the SHAPE
extension, so that you can watch the background or underlying window
through this hole.
While xcompmgr is running, the window isn't updated correctly. I tried
this using fluxbox (which itself has some problems with X11 SHAPE), but
it also happens with openbox, icewm or windowmaker, it even happens when
not using any windowmanager at all. I tried using compiz as compositing
and window manager, but failed getting it to run even halfway.
The system is an old Mac Mini, using an ATI Radeon videochip and running
a current Debian/testing system.
Give me some feedback if you can't reproduce this, I'll try to circle
in the other factors then.
Cheers!
Uli
