Suspecting: r463150 ?

Kindly help to re-assign, if your changes are not cause for this issue.

Couldn't reproduce on 59.0.3066.0 on macOS 10.12.3, Intel HD 6000. Just to confirm, by NTP you mean new tab page (i.e., put the bookcase in a background tab)?

Reporter: please copy+paste the contents of chrome://gpu from the affected systems to this bug report. This is needed for WebGL and GPU related reports.

With response to comment #2:

Able to reproduce the above bug on Window 7 OS for Chrome version - 59.0.3067.0 (Official Build) and Open 'New Tab Page' means putting Bookcase WebGL experiment in a background tab (pervious tab)

Please refer the attached copy of about://gpu.

My patch should not have any functional change. I do not have access to a windows machine to test. Assigning to jbauman to help triage.

Unable to reproduce on recent builds.

abombde@ are you able to reproduce this in more recent Chrome versions?  Perhaps this is a v8 regression that was already fixed.
