User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.47 Safari/537.36 Steps to reproduce: The attached HTML creates a WebGL context and starts up a requestAnimationFrame loop which clears the framebuffer to blue 1000 times and then clears it to red. Note - this does not appear to repro on Aurora. Actual results: The WebGL context will occasionally flash blue, indicating that Firefox is displaying a framebuffer that we haven't finished drawing yet. Expected results: The WebGL context should always appear red.
OS: Linux → Mac OS X
Hardware: x86_64 → x86
Clarification - this only repros under OS X.
Component: Untriaged → Canvas: WebGL
Product: Firefox → Core
What Firefox version does reproduce? 20.0 as in the 'version' field? The UA string in comment 0 doesn't look like Firefox.
Firefox 20.0
This seems fixed in Firefox 24.
Great, I'm going to mark this WFM. Please reopen if this is still broken for you.
