kevin: user reports GPU process taking up over 2GB |
|||||||
Issue descriptionChrome Version: 56.0.2924.104, 57.0.2987.146 OS: Chrome OS Two feedback reports. Same user: * Report=54068673739 * Report=58738057593 GPU process shows as taking 2.5 GB. ...it's causing OOM kills, but the root cause is really that the GPU process seems to be eating like there's no tomorrow.

Additional feedback reports: * 59244935859 * 59246310635 * 59332514589 * 59329526708 * 59404534233 All feedback reports are captured on kevin. I have never been able to reproduce this problem on my other Chromebooks (Acer C720, Chromebook Pixel 2015), so the problem is device specific (though not necessarily specific to kevin). Video of crosh top showing GPU process rss memory growth: https://goo.gl/photos/Z4Sa6GGmtyD3jMKK6 The video also suggests a possible renderer memory leak, which should be tracked separately. See attachment for memory-infra trace captured while reproducing the problem. I have been using the following repro procedure, which typically succeeds in introducing the problem within an hour of trying. * Play one of the DailyMotion videos (labeled DM) from http://maplestage.com/episode/p29qO/%E7%84%A6%E6%80%A5%E7%9A%84%E7%BE%85%E6%9B%BC%E5%8F%B2-%E7%AC%AC6%E9%9B%86-My-Secret-Romance-Ep-6 * Watch GPU process RSS memory from top. If GPU process memory remains below 500MB (as opposed to jumping to around 700MB), the problem is most likely not happening. Reboot and try again. * It may help to leave the system off for a few minutes before turning it back on. (This is getting into cargo-cult territory, but who knows).

From the above steps, one thing that's kinda odd is that it happens sometimes but not other times. I wonder if perhaps it depends on what video quality you end up getting? This video site appears to default to "Auto" quality, so perhaps depending on the speed of your internet connection you might get 720p, 480p, 380p, 240p, 144p, ... ...and maybe the problem only reproduces with one of those quality settings?

...or, I suppose, it could also matter what advertisement is served to you. I wonder if an add blocker would make the problem go away?

Comment #5, I see this as a YouTube Red member as well, so ads don't appear to make a difference. Just a long YouTube TV or Netflix session with a couple of tabs open has me hitting swap.
