After some time Chrome seems to develop this condition where it won't come to the foreground but sits behind other apps even if I click it, why I think it's related to DisplayFusion is because when I use non Windows taskbar (rather one created by DP on another monitor) to minimize and maximize Chrome it becomes top most window again, also if I close DP the bug fixes itself and I can just click Chrome and it becomes top most window like it should. Is this a known bug of DP or is it Chrome-related?

Yes and by the way I think this may have started happening once I changed that.
