So, what has started to happen over the last few Chrome versions (On 59 now, and it also happens on the latest 61 Canary build) is that when I minimise Chrome, and then maximise it, then there are thin vertical bars on the edge of the window (one on each side). If I restore the window size to basically not maximised or minimised then maximise it, then it's all fine.

I've worked out that it's a 4K problem. So my setup is a 4K laptop, with 2 1080p screens. I've set the main display to be one of the 1080p screens.

So the issue only happens when I min and then max on one of the 1080p screens. It works fine if I do this on the 4K screen, or if I reduce the 4K screen to 1080p (don't want to do that), or if I make the 4K screen the main display (fonts are not smooth then on the 1080p screens). So yeah, 4K issue somewhere there.

Interestingly it was all fine until I think just after the last main Win10 update (Creators update I believe), and I have noticed that windows act a bit more weird now when moving from one screen to another (eg. Win button plus shift and then an arrow left/right). They may resize for example unexpectedly. It was a lot more stable before the last Win10 update.

Note though that I don't get this with any other app as far as I can see. Firefox/IE/Edge work fine for instance.

Anyone got any ideas, that would be great as it just gets a little annoying after a while (main window area is slightly smaller so some things that resize don't look as they normally should - eg. FVD speed dial).
