+Rachel for desktop triaging (as gCon PM rotation duties)

This only seems to happen with a theme applied (at least on Windows 10 Home Edition, Version 1607). With Chrome's default theme, fullscreen works as expected.

I have a dual monitor display and this only happens on my secondary monitor that does not have a taskbar. Chrome is fully default without any themes and this issue still occurs for me. If something is fullscreen on my main monitor, for example, a game, then the chrome video on the secondary monitor will not go fullscreen and no amount of minimizing and maximizing will allow it to go fullscreen. A workaround I have found is that if I close the fullscreen game on my primary monitor, chrome will then allow me to make the video on my secondary monitor fullscreen. However, if I open the game back up, and I need to minimize the fullscreen video on the secondary monitor(For example, look at the chat in a twitch.tv channel), upon attempting to make it fullscreen again, the video reverts back to showing part of my desktop.

This issue is still occurring on all versions. Can we get an update on it?

Does this occur on Mac? I can't reproduce this at all

This issue still occurs on Windows versions of Chrome. I am not sure if it occurs on the Mac version.

If Chrome has a theme applied and then put into Fullscreen mode on a monitor that does not have a taskbar, the issue will still reproduce every single time.

Yep, 60.0.3112.101 on Windows 10 Pro 1703 x64. Theme + no task bar on that monitor + full screen Video = Border.
