I am not sure where to start and seek for input on a problem with KWin and
Compiz. They show very similiar wrong rendering of borders, shadows and
the logout screens.
In compiz is a RGBA buffer used to contruct window borders and shadows:
/* all pixmaps are ARGB32 */
format = XRenderFindStandardFormat (xdisplay, PictStandardARGB32);
A sreenshot suggests that the 8-bit buffers are blended as is into the
30-bit visuals. What is the correct way to blend in the final frame buffer
image with XRenderComposite()?
As a side note, the window contents are almost fine with the exception of
FF and GTK2 drawing areas.
kind regards
