There is  a blue vertical line that appears at the right corner of the panel, it gradually moves to the left corner and then disappears. It moves with a speed like 2px in a sec. It happens once in a month or so and I have no idea how to reproduce it. And I have never seen this line anywhere outside the panel.  

About one and a half of years ago I switched from the bottom panel to the right side panel. And since then I experience this really weird bug.

Maybe it's somehow related to the hardware, especially to the Intel graphics cards. Previously I was using a Laptop with the Intel HD Graphics 4000. Right now I'm using a laptop with the Intel UHD Graphics 620. And I've seen this bug on both of them.

Here're a couple of screenshots
