I am hitting this assertion a lot on nightly with e10s enabled.

This doesn't reproduce for on Windows or Linux debug trunk builds. How about you, Doug?

Sounds like more information on your environment could be helpful. Can you please copy & paste the Graphics section of about:support?

Also try running a debug build with an envvar of "MOZ_GL_DEBUG_ABORT_ON_ERROR=1".

Using a local cached copy, and with "MOZ_GL_DEBUG_ABORT_ON_ERROR=1" seems to detect no other errors, and it still fails at: Misprediction: Bound read FB predicted: 6. Was: 5. Assertion failure: false (Read FB binding misprediction!), at gfx/gl/GLScreenBuffer.cpp:315

The URL is dead (and I can't revive it with a Wayback machine), are the contents saved anywhere?
