@cbiesinger : Could you please help to reassign if your change is not the cause for this change.

That patch did not cause this bug. Any chance to get a bisect with a smaller range?

mnikam@, Could you please narrow bisect the issue as per comment #4

My CL only touches tests.

@phulce not sure if we really have an owner for the application panel, so can you take a look at this?

enne's change, perhaps?

"Turn on enable begin frame scheduling by default"

I can't seem to reproduce this behavior on OS X 10.11.6 and the screencasts unfortunately don't capture any flickering. Are there any other necessary circumstances/settings that might be missing from the repro steps?

@ mnikam:

Could you please update on comment#11.

Thanks!

@ mnikam

Thank you for rechecking, but the attached screencast does not show the issue you've described, unless I'm misunderstanding what content is flickering (you're not referring to the tooltips, correct?). I cannot reproduce on the identified versions with the given the repro steps described/shown in the video alone. Are there any other system or Chrome settings you can think of that you have enabled that might be out of the ordinary?

With response to comment #14 :
Note : There are no other system or Chrome settings I think have enabled.It is also reproducible on fresh profile.Please press 'Esc' key to open console drawer and then try the mentioned steps.Observe the application window on left side of devtools.Flickering is observe after closing the newly open tab.

Yup. I can repro. :)

@mnikam sorry for the miscommunication I am able to reproduce the jitter of the console/devtools window shifting up and down now thank you!

Still able to reproduce the issue on Mac 10.12.2 using latest chrome version 57.0.2984.0

pfeldman@ Could you please look into this issue.

Thanks!
