You find this old bug when the task bar is at the top of the screen. As far as I know this render bug was never vanquished.
Just recently, I noticed a weird thing with my taskbar that is driving me nuts! It overlaps a teenie bit into my desktop and leaves a faint silver line at the top of my screen. I don't know where it came from, and I want to make it go away! When I auto-hide, it still leaves the little strand or what looks like the taskbar shadow on the desktop.
Here's the image of my taskbar, and hopefully you can see the shadowish line at the bottom:
Any ideas on how to make it go away? Thanks in advance!
