Hey guys, Been having this issue for the past week or so and I cannot work out what the heck it is. I can be doing anything on my PC and a window 'flashes' on my screen, I have no idea what it is as it doesn't seem to show up on Task Manager and I have not been able to catch a screenshot of it yet. It seems to happen regularly and is most noticeable when playing a game in borderless windowed mode as it basically alt+tabs me out of the game. I can see the window when it pops up but its so fast I cannot work out what it is. It's insanely annoying! Does anyone have any idea how I can stop it? I have tried a couple of 'fixes' I found after a quick google but nothing worked. I have run Malwarebytes, AdwCleaner, CCleaner, Glary Utilities and nothing so far has found or removed the issue. I am running Windows 10 btw.
