There seems to be an ugly visual bug on the login screen if you use Windows 10's Edge browser. I tried to take screencaps of this problem, but the visual bug wouldn't show up, but it's still there. I had to take a video of the screen using my phone, pardon for the quality.
When I hover over the login boxes, the login text vanishes. And when I click on the text boxes, some weird artifacts start fogging up the screen and the text boxes start vanishing.
