I wasn't able to reproduce this on my ubuntu machine with esr52, or on any OS in nightly. Since it's webgl, it might be driver-specific corruption? I was running with nvidia's proprietary blobs.

Possibly.  My test system is using the default Ubuntu 16.04 video drivers.  Also, I just confirmed that this issue still triggers using the esr52 rev d61516b059c1.
