I wasn't sure if it was the windows manager or the x server that was doing this. Either way, when opening a new application the driver gets flooded with cursor updates as something is animating a spinning cursor. Since the refresh rate is only 60Hz, I see a very long hang in the desktop(several minutes) where nothing responds. SSHing into the RPI still works though even though it appears hung. I had a few people on the net test the changes and they all report that without the change xfce4 and gnome are both unusable on the RPI. With the change, things work fine. Not waiting for the vblank on cursor updates is what other drivers appears to do as well... _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
