Details

There are some pauses in some WebGL demos (like www.ibiblio.org/e-notes/webgl/deflate/shark_anim.html) that sometimes causes the FPS to highly decrease from 60-70 FPS to 10-20 FPS. I think this is due to garbage collection, but I'm unsure. Probably duplicate of bug 482853 (that is about canvas3d), bug 504640 or bug 624867. We should correct these and see if the problem disappears.
I see the issue also under Linux, with latest NVIDIA drivers.

The demo has ~350ms GCs, so probably the bug is due to these. Infact the rendering pauses happen exactly during GCs.
