Issue descriptionUserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 Steps to reproduce the problem: 1. Open the test case HTML page (requires an HTTP server for the image load). 2. 3. What is the expected behavior? Renders a "This is WebGL" texture on a full-screen quad. What went wrong? Draws nothing. Did this work before? N/A Does this work in other browsers? Yes Chrome version: 58.0.3029.110 Channel: stable OS Version: Ubuntu 16.04 Flash Version: On line 120 of the test case, if you set the TEXTURE_UNIT variable to 1, it works, so it seem to just be a problem with binding to unit 0. It also works if you just remove the call to bindSampler on line 127. Works in Firefox 53.

(Note: in order to reproduce I used the version of this test case from https://github.com/tsherif/webgl2bugs since it contains the image) I'm able to reproduce on my Linux/NVIDIA machine, but not on my macOS/Intel machine. Probably driver specific.

I don't think this is a regression, so it doesn't need bisect.

Also does not reproduce on Windows/AMD or CrOS/Intel. Marking as NVIDIA-specific.

What are the contents of about:gpu (plaintext please) from an affected machine? I'm surprised this would be broken in NVIDIA's drivers. Olli, any chance you can confirm this bug?

Also, if it works in Firefox on the same machine it's almost surely a bug in Chrome. Can you please confirm that the fix for Issue 713127 didn't fix this? Please try Dev Channel (google-chrome-unstable).
