Hi, I'm using clutter 0.6 with ohand's official debs on an nvidia config in dual screen (TwinView), one big ([EMAIL PROTECTED]) and one smaller resolution ([EMAIL PROTECTED] or [EMAIL PROTECTED]). I noticed that video textures get teared (horizontal lines such as in attached file), on both screens when the subject in the video is in relatively high speed motion.
I upgraded my hardware (now 9600GT), without success. On single screen setup, no changes either. I hoped using VSYNC would do the trick (seems to be the number one recommendation for video tearing effects), yet when i tell clutter to enable VSYNC, my app seems to run fine @60 fps except for the videos that are very slowly rendered, making them unwatchable. * Can anyone explain me why this happens ? * Is it due to cluttergst's design, texture update rate/steps ? * When/why use CLUTTER_VSYNC ? * can clutter do triple buffered VSYNC ? * dynamic TwinView is said to force VSYNC with only one head of the graphics card. Doesn't seem to be my problem since both screens show tearing artifacts Any other suggestion would be more than welcome ! Kind regards, Florent
