Hi Timea,
Thanks for reporting - would you mind showing me a screenshot of these white borders? Or a video showing you causing them to appear? I want to see if this is a dupe of bug 1543027, or something else entirely.

Here is the screen recording for Windows 10 x64 on latest Nightly: https://streamable.com/6r5kt
On Windows 8 a full white border will also start flickering upon focusing. I will attach a screen recording for that too.

And here is the recording on Windows 7 (same as it can be seen on win8). Ignore the spiky video, the screen recorder causes it.

I'm not 100% sure why this fixes the issue, but I suspect it's because we used to set chromemargin
on the window after it had had a chance to lay itself out. It seems we can sidestep the issue
by putting the chromemargin on the <html> node directly.
There's the remaining issue where due to rounding, sometimes a very thin (1px) white border will be
displayed around one part of the player window. This has been split out to bug 1549542.

This is still reproducible on latest Nightly71 on amazon prime videos, see recording for reference.
Mike, should we open a new bug or re-open this one?

Let's open a new bug with these STR, thanks Timea. Does it reproduce reliably?

Hey Mike,
Tried a quick test for it but couldn't reproduce it on the first time and I can't really recall if I did anything weird when I encountered this issue.
I'm a bit caught with other feature testing but will submit a new bug for this if I can reproduce it again.
