Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3350.0 Safari/537.36 Example URL: https://s3.amazonaws.com/storage2.interlude.fm/dev_temp/tomer/chrome_vp9_canvas_bug/index.html Steps to reproduce the problem: 1. On Windows Chrome 66, navigate to provided URL 2. Watch the VP9 video drawn onto a canvas element What is the expected behavior? Video should be displayed correctly. What went wrong? Every once in a while, entire window will go black for a few seconds. Not only the web contents, but also the address bar and top tabs area. Did this work before? Yes 64 Is it a problem with Flash or HTML5? HTML5 Does this work in other browsers?

Thanks for filing the issue! Unable to reproduce the issue on reported chrome version 66.0.3350.0 and on the latest stable 64.0.3282.168 using windows 10 with the below mentioned steps. 1. Launched Chrome 2. Navigated to https://s3.amazonaws.com/storage2.interlude.fm/dev_temp/tomer/chrome_vp9_canvas_bug/index.html We observed the video being played with out any black screen in between. Attaching the screen cast of the same. @Reporter: Could you please check the screen cast and let us know if we have missed any thing in the process of reproducing the issue. Any further inputs from your end may help us.

Thanks for trying to reproduce! Looks like it does not happen on your machine. I've now tested 4 Win10 machines, and was able to reproduce on 2 of them. Please note: 1. On affected machines, it reproduces easily and consistently. Probably GPU related. 2. Does not seem to happen with H264 video. 3. When it happens, the entire browser is affected, not just the webpage content. 4. This is a regression - works fine on Chrome 64, but occurs on 66. Please see my attached screen cast.

We're seeing a sudden rash of these black frames on canvas bugs; some recent gpu change?

Checked the issue on reported chrome version 66.0.3350.0 using another Windows 10 machine, still we are unable to reproduce it from ET end. We are able to play the Video with out any black screen in between. Attaching the GPU details of the machine in which the issue is tested. Removing Needs-Bisect label as we are unable to reproduce the issue from our end. Please feel free to add it back if required. Thanks!

This is probably passthrough vs not. The following log is suspicious: [11900:18188:0220/171527.539:ERROR:gles2_cmd_decoder_passthrough_doers.cc(4139)] : NOT IMPLEMENTED (or not, DiscardBackbufferCHROMIUM can be implemented as a noop). But that would explain why it only affects 50% of the machines (we have a 50% experiment).

I'll look into it.

reporter: Are you still able to reproduce this issue? Changes have been made to the VP9 hardware video decode path that may have resolved this issue.

Can no longer reproduce - looks like it's fixed. Thanks!!
