Yunchao, can you take a look at this? At least you should have access to Linux Intel.

I think this issue is a duplicate one with https://bugs.chromium.org/p/chromium/issues/detail?id=644740. And the fix has been submitted yesterday at https://codereview.chromium.org/2409523002. Could you take a look, Zhenyao and Corentin? 

https://build.chromium.org/p/chromium.gpu.fyi/builders/Linux%20Release%20%28ATI%29/builds/49409 has https://codereview.chromium.org/2409523002, but still fails.
Going to suppress this failure while it's being investigated.

Are they still failing? The fix should have landed already.

The fix didn't work.

As my comments in https://bugs.chromium.org/p/chromium/issues/detail?id=658832. The failures for blitFramebuffer (default_framebuffer_00.html and blitframebuffer_filter_outofbounds.html and framebuffer_test.html) are two issues: 
1) specific driver bug for Linux AMD (can anyone work on this? I have no Linux AMD machine, and it is not very suitable for Intel guys to fix AMD specific issue)
2) add some workaround in angle project(I suppose that Corentin is working on this), the logic of the workaround should be similar to this change for Mac and Linux Intel/AMD: https://codereview.chromium.org/2409523002.

Please re-assign it to me if I can help.

We will look at 1) (or just leave the suppression until we look closer at AMD). I will take care of 2), there's a couple things from your changes I still need to replicate.

OK, thank you, @cwallez.

WebGL CTS: remove now passing expectations.

Most of them come from implementing a work around for blits on Intel.

jdarpinian: Would you be able to confirm if this is still an issue?  Thanks.

I've confirmed that the test is passing on Intel but still failing on Linux AMD. Because we are not planning to attempt a conformance run on Linux AMD I have not added this to our list of conformance bugs to fix.

Could we remove any remaining suppressions for Linux Intel, change the summary of this bug, and close this as WontFix? Perhaps we should add comments to the suppression file for WontFix'd bugs like this one, to save ourselves time when revisiting things.

All the Intel suppressions are removed. When we get Linux AMD bots with updated hardware we will reevaluate all the AMD test suppressions.
