Windows Flashing screen when plugging in PS controller



Hey I hope it's ok to post this issue here since I don't find it's programming related.

I have a player (GM:S 1.4 Windows build; player uses Windows 10 and PS4 controller plugged w USB) and he is reporting that after plugging it in the game surface starts "flashing". Has anyone heard of a similar error? I am on a Windows 10 computer too with both OS and Xbox controller and have not ever experienced this issue.

What could cause this error, I wonder, not being solid in hardware tech. I reckon it's his hardware, but what part other than the graphics card could it be?
