Able to reproduce the issue on one of my Windows machine which has attached GPU details, Unable to reproduce on Mac and Linux machine which I have.



Bisect result :

Last Good build : 63.0.3220.0 -- 502993  

First Bad build : 63.0.3221.0 -- 503308 

Change Log : https://chromium.googlesource.com/chromium/src/+log/63.0.3220.0..63.0.3221.0?pretty=fuller&n=10000


Note : Due to new machine exceptions I wasn't able to perform narrow bisect hence performed the manual bisect(Working with Techstop to get this resolved).

URGENT - PTAL.
M63 Stable promotion is coming soon and your bug is labelled as Stable ReleaseBlock, pls make sure to land the fix and get it merged into the release branch ASAP. Thank you.

Going to do a quick bisect.

I ran python bisect-builds.py --use-local-cache -g 499098 -b 508578 -a win64 -- https://cad.onshape.com/documents/3bd144e9d07128b23daaa194/w/dfd7445ab6dce84f2b2b621c/e/fd9047327da21caec41aae82

And got this result:

You are probably looking for a change made after 503520 (known good), but no later than 503533 (first known bad).

One ANGLE roll:

https://chromium.googlesource.com/angle/angle.git/+log/47bf2dc..1f9d684

A lot of suspicious CLs in there with dirty bits. I'll do a narrow ANGLE bisect.

enowak@onshape.com thanks for the bug report and repro case.

I found the culprit CL, which was mine:

D3D11: Minor optimizations to vertex attribute application.

https://chromium-review.googlesource.com/666048

Likely a problem with dirty bits for current value attribs. Looking now.

Fix and regression test in review now.

The following revision refers to this bug:
  https://chromium.googlesource.com/angle/angle/+/9088557fe47e0ce1487b248b60acbc740acd7801

commit 9088557fe47e0ce1487b248b60acbc740acd7801
Author: Jamie Madill <jmadill@chromium.org>
Date: Tue Oct 31 01:40:16 2017

D3D11: Fix dirty current value updates.

Fixes a bug where subsequent updates to a "current value" (disabled)
Vertex Attribute would not trigger the state change to D3D11 such that
the updated buffer handle would be applied to D3D11. Also adds a test
to cover the problem case.

This bug was introduced in 2bc947334cad:
"D3D11: Minor optimizations to vertex attribute application."
