As shown in the photos below, my taskbar is not auto-hiding correctly. Yes, it is set to auto-hide. I have restarted windows, and restarted my browser (google chrome). I even tried using a different browser, which made no difference. No, there are not any hidden icons on my taskbar that are calling for my attention. I have Windows 10.
The problem is, before this started, that red line you see at the right of the first image, would COMPLETELY disappear when I used fullscreen mode on any website. I like it that way, and I have no idea why my computer stopped doing that since I did not change any settings whatsoever. If I move my cursor to the right, I will make the taskbar appear, which is NOT what I want. I want to be able to move my cursor all over the screen when it fullscreen mode, and for that taskbar to not be visible in any way, shape or form.
