Answers (N/A if not applicable)
Provide a detailed description of the issue
Every time a game enters full screen, the screen flickers (showing black background with lines of various colors). It also happens whenever I wake the laptop from sleep after clicking the mouse. A restart of the laptop is needed to make the screen stop flickering.
Please place an X to the right of the option showing how often you see this issue using specific steps. (Ex: 'Every few times a game is started it flickers.' <- This would be "Often")

* I have found 2 "band-aid" solutions, but it doesn't work for all games/software. I checked the "Disable display scaling on high DPI settings" in the Compatibility tab under the .exe properties and I simply ran the game in Windowed mode (borderless).
Another "band-aid" solution I found involves disabling the Intel HD Graphics driver in the Device Manager and just using discrete graphics, but I would like a permanent solution to the problem.
I have read and tried the solutions in Post #85 of this page: Intel HD Graphics 530 driver causing screen flickering, but all didn't work.
Attached are the outputs from Intel SSU, DxDiag, DispDiag, as well as the hardware stepping. Thanks in advance.
