testdrive-archive.azurewebsites.net/performance/fishbowl showed flickering on my Win10 PC with nightly. It did not saw it in the past.

I'm unable to reproduce this problem on Win10 with Nvidia GTX 1060. But after I was reading in another tab and switched back to Fish Bowl's tab, it had a red background for a fraction of a second. Then I noticed that if I click on "Trigger Device Reset" on about:support I see the blue water as background for the whole page. If I click on "Terminate GPU Process" the whole page is red. Both can be fixed with F5. Without WebRender, the page has the buggy water background in both cases.

Hmm, I just updated nightly, then I could not reproduce the problem.

Yea, the problem seems to related to "Device Reset" and "Terminate GPU Process".

The following STR seems to reproduce the flickering for me. [1] Start Firefox [2] Move to about:support and click on "Trigger Device Reset" [3] Move to https://testdrive-archive.azurewebsites.net/performance/fishbowl/ If the problem does not happen continue [2][3].

Part of the problem might be addressed by Bug 1469480.

The following STR is valid on my Win10 PC(P50). [1] Start Firefox [2] Move to about:support and click on "Ternimate GPU Process" [3] Move to https://testdrive-archive.azurewebsites.net/performance/fishbowl/

The flicker actually caused by the video of water. https://testdrive-archive.azurewebsites.net/performance/fishbowl/video/water.mp4

When the problem happned, there were the following error messages. > GP+[GFX1]: RenderDXGIYCbCrTextureHostOGL AcquireSync timeout, hr=0x80070057

The problem might be a driver specific problem. I did not see the problem on my Win10 PC with NVIDIA GeForce GTX 960.

When the problem happened, IMFYCbCrImage was used in content process to hold video data.

IMFYCbCrImage usage might cause the problem. IMFYCbCrImage does not recycle ID3D11Texture2D and create ID3D11Texture2D just before forwarding to GPU process.

attachment 8987007 [details] [diff] [review] in Bug 1470386 address the problem for me.

Confirmed that the issue was addressed on latest nightly with Bug 1470386.
