Comment 3 for bug 408065

Hello,

I'm part of the Cairo-Dock Team.
We confirm this bug. There was the same problem with Intel graphic cards but all seems ok now (Ubuntu Karmic - 13 Aug 2009) (even with an Eeepc701 while having multiple visual effects and remains fluid!).

We think that this black background with ATI cards is due to this function 'GL_EXT_texture_from_pixmap' in OpenGL. We suppose that the composite support needs to be improved.

I don't know how can we help you but we can try to answer to all your questions !

The problem is the same with Catalyst 9.7 (black background and some artifacts in indirect rendering mode)

You can also test with an the indirect rendering mode :
   $ cairo-dock -o -i

Thanks to mac_v for having reported this bug. And thanks to Bryce for having confirmed it !
