Is this problem only specific to Dolphin and ESPN? does it show up in other sites serving full screen videos such as CNN, android browser shell. 

This app is not even using WebView. And we can't reproduce this issue locally. To verify this is not using webview, you can add --show-composited-layer-borders to command line args.

sgurun@, For now I'm seeing the issue only on dolphin/ESPN 

Note:-
-I checked on Android Webview Shell  browser on ESPN, There is no option to make Video to full screen and I'm not layout over laying issues.
 
-And checked Dolphin on CNN/BBC/NBC I'm not seeing this issue.

hush@, can you please make sure you are disabling in the jetpack to usewebview

Under "setting > Disable Jet pack", then you will see the comment line border

adding rbs back. satya demoed the issue on a samsung phone. 

definitely can't repro on nexus 5

hush reproed it on a Nexus5xp

revert of https://codereview.chromium.org/1907753002 works. My understanding is this means we have to choose between crbug/603521 and this

issue 603521 doesn't affect M51, so go ahead and revert from M51, we'll keep the other issue open for M52.

https://chromium.googlesource.com/chromium/src.git/+/3d7916e49d626af16940e9d8148e655d436b669d is the landed revert.  We should be good to go.

Actually, sorry - I'm going to leave this open and target to M52 as RB-Stable as we'll still have to address this once the unified pipeline is turned back on.

Verified/fixed on M51(latest web view build)/S7/ATT

Will leave the bug as it as for M52 as per above comment.

Disable drawing of video backgrounds in OverlayFullscreenVideo

This is a follow up to http://crrev.com/1907753002 to fix cases where the
video background is now visible in OverlayFullscreenVideo, where it's not
desired. This forcefully stops the GraphicsLayer associated with the
video from drawing its content (in particular, the background) when OFV
is enabled.

I have confirmed this fixes the bug in Dolphin and elsewhere.

Your change meets the bar and is auto-approved for M52 (branch: 2743)

I'm seeing this issue on DU browser/ESPN as well

With which build? The fix only went in 4 hrs ago. So unless you're testing with a tip of master build, you won't see the fix.

This was merged to 52. It did not make it into 52.0.2743.49 though. It will be in the next one. I'll leave this open to verify on the next beta. 

This issue has been approved for a merge. Please merge the fix to any appropriate branches as soon as possible!

If all merges have been completed, please remove any remaining Merge-Approved labels from this issue.

Thanks for your time! To disable nags, add the Disable-Nags label.

Thanks for verifying

Merge for m52 already happened?

Yep. The script that usually posts comments isn't working apparently so I updated the labels

marking verified
