Description Matthieu CASTET 2007-08-11 05:49:13 UTC 
Hi,

in EXA mode with nv17, composite extension is enabled by default. This result in fifo hang. [1]

The hang happen in the NVComposite function.
Removing composite hook fix the problem.


PS : xv blitter that use the same object (NvScaledImage) works fine.

This is the blending that is broken, copying works fine.
Worked around the problem by disabling blending in NVCheckComposite() upstream, and I have a tentative _fix_ (hardware blending works) in my public repository.

corrupted avatar in gajim

with the last git version (fix with beta1 and beta4), there is some image corruption.

With gajim, avatar with transparent background get corrupted if a another windows is moved over them.

This will go away with the new 3D-engine-based EXA implementation for NV10-NV20.
