User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 Steps to reproduce: 1. Start firefox with a new profile (to make sure it's not due to anything wrong with my profile). 2. Visit http://www.vsynctester.com/ and look for the fps and smoothness of the animation. 3. Switch between windowed or fullscreen mode by clicking the fullscreen button on the window frame. Firefox Stable 51.0.1 and Nightly 54.0a1 (2017-02-05) on macOS 10.12.3 with Intel Iris Graphics 6100 1536 MB Actual results: The page rendering is out of sync with the display (60Hz) as indicated by fps and the graph, as well as the red/cyan text. The animation is choppy. Switching to fullscreen helps a little bit. But the performance is still not comparable with Safari or Chrome. In the graphics section of about:support, the failure log shows three entries of CP+[GFX1-]: Failed to create a SkiaGL DrawTarget, falling back to software Expected results: The graphics should be smooth and correctly synced with display. Expecting similar results to Safari and Chrome.

I believe this is similar to bug 1161818 as layers.shared-buffer-provider.enabled remains false.

Component: Graphics → Canvas: 2D
Setting layers.shared-buffer-provider.enabled to true doesn't seem to make any improvements here.
