Description Patrick Libert 2006-04-10 08:35:49 UTC 
When I use Pixel (a photoshop like program based on libsdl)
on Ubuntu Linux with the latest XGL server activated, Pixel gets transparant.
Appearantly, SDL doesn't work as it should be with the latest XGL server.
When I dissable XGL, Pixel works again.
Is libsdl to be changed so that it is compatible with XGL?
The author of Pixel (Kanzelsberger) adviced me to report a bug on the libsdl website.

Is this definitely a bug in SDL, as opposed to a bug in XGL ?
Comment 2 Sam Lantinga 2006-04-15 12:06:01 UTC 
This is definitely a bug in SDL.  However, I haven't had any luck in getting any compositing manager running on my system, much less XGL.  Does anyone have any suggestions or instructions?
Comment 3 Sam Lantinga 2006-04-17 00:53:54 UTC 
On servers with the composite extension enabled, visuals with 32-bit depth
have an alpha mask.  This is pretty neat, but SDL needs a bit more work to
handle these properly, so for now, we'll just use 24 bit depth visuals.
