Windows 10: Weird overlay on applications

Whenever I open some specific applications, weird lines appear over them. I am attaching a screenshot for reference. Whenever I move my mouse pointer over these lines, they disappear but they reappear after a few seconds. Any ideas how to fix this?

Radeon Overlay not displaying all options

Ok, I got a question. The options to hide the overlay are confusing. What are the steps to turn on the overlay in-game? Not interested in logging much at the moment. Is Alt-R part of turning it on/off?
