Description Giacomo Perale 2008-03-29 12:07:38 UTC 
Commit 978145a075255ae153ee05c2a037400e61558079 "Set param_var->param_binding_type = PROGRAM_CONSTANT" broke the water effect in compiz on my rv370 card. 

When I activate the effect, the screen becomes black with colored bands covering approximately the top 10 and bottom 10 pixels and I can see the "wave edges" in white moving through the screen at a frame every 1-2s.

When the effect ends the screen stays mostly black, but when I activate the other effects it's possible to see some changes, and occasionally white borders where windows should be. The speed remains very low (~1 fps).

Nothing on the logs, I bisected until I found the guilty commit.

PS. I'm not sure if the bug is common or r300-specific, so assigning to dri-devel.
