Per offline discussion, fkp found a workaround on his side and we will revisit this later.

Forgot to mention: the workaround is to use float textures instead.

Please provide at least some detail about what the bug actually was, and whether it's feasible to write a WebGL conformance test for the issue.

We don't understand the nature of this bug because it either requires fkp to write a standalone test case for us to take a look or us to learn how to study and debug his codelab in Google3.  Currently neither seems a top priority task. However, we should definitely come back to that.

This issue has been Available for over a year. If it's no longer important or seems unlikely to be fixed, please consider closing it out. If it is important, please re-triage the issue.

Sorry for the inconvenience if the bug really should have been left as Available. If you change it back, also remove the "Hotlist-Recharge-Cold" label.

Should we wontfix?

So far this is the only complaint without a reduced test case. It's very likely there is a bug in the client code. Closing as Won't Fix for now.
