Ok, so here I have 2 issues:
1 - Apparent vertical sync problem
Here's a screenshot of the problem
See that line? it looks like the next frame of the video, as if it's out of sync. You can notice it a lot in videos with a lot of movement. Also, it's a lot worse if use the HDMI output to a TV or monitor or when I go fullscreen.
That particular screenshot was using Flash player. But it's the same (if not worse) using HTML5.
This doesn't happen in Firefox or Chrome, or using desktop video players. The performance there seems fine.
2 - Sharp borders/edges (like a badly resized image, with no anti-aliasing).
Compare these two images (FF left, Chromium right):
Things I've tried:
- Changing the value of "Sync To VBlank" in CompizConfig (to false, then to true)
- Disabling hardware acceleration in Chrome
These is what I know about my video card (using lshw -c video
):
