Thanks for the report. You'll need to look at parent_got_angle_revision for this bot to find the regression range, since it is not a swarming bot. It pulls in the ANGLE revision from the parent builder (Linux Release GPU FYI builder).

In this case the ANGLE regression range contains this CL:
https://chromium.googlesource.com/angle/angle.git/+/9250cb248203c00850f4a91d804dede3b9907cbe

Which seems suspect. Olli can you take a look?

I'll add a suppression for the test: https://chromium-review.googlesource.com/#/c/434080/

Unassigning myself, working around or getting a driver fix for the AMD-specific issue is not a priority for NVIDIA. I might still take this later if it's required for release of GLES 3.1 extension for WebGL.

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.

For more details visit https://www.chromium.org/issue-tracking/autotriage - Your friendly Sheriffbot

This bot's been changed to use an AMD R7 240 but angle_end2end_tests doesn't seem to be running on it any more. Closing this as there are other higher priorities.
