Hi Ryan,

Unfortunately this bug is still reproducible using the STR from comment 0, on latest Nightly 63.0a1 (2018-06-27) running macOS 10.13.

Huh, so I can reproduce this.
The console is full of this spam, however:

However with that pref disabled, everything seems to render fine!

This is probably us messing up a texture format. I'll run it in a debug build, which should show if that's the case.

Jeff, were you able to investigate more on this bug? Thanks

Jeff, any news? I would take a low-risk patch for beta as it affects a major site.

Emil, could you confirm that you are still experiencing the bug in 63/64 on macOS? Thanks
