I know that this question/problem has come up before, but I don't think there is any resolution to it.
I've got Ubuntu 13.10 running atop kernel 3.0.17, running X11, and Chromium v 35 on that. Chromium is GPU accelerated (except for WebGL), and I'm writing an app in HTML5 which requires GPU accelerated CSS3 transitions. Hardware is a Wandboard Quad; although that won't necessarily be my end hardware (it was a good development platform for my needs).
My animations run at a gorgeous 60FPS. BUT, it tears because of the v-sync issue where the IPU is not properly passing the signal to X11.
I do have a custom application that runs on the framebuffer to accomplish one portion of my animation, without any issue. But it is a deal breaker for me to not have the other portion of my application in HTML5 without tearing.
My questions are;
1) Is this in the pipeline to be fixed? If so, ETA?
2) Does anyone have any advice/suggestions on a fix?
3) Is there any way to make this a priority if it is not in the very near pipeline? I'm looking at a very aggressive Q1/2015 production date, with significant volumes.
