I know this is the hardware forum, but if there is a tech help forum I couldn't find it. This has been happening to me a lot in windows 10 lately. I tab out of a game and most of my screen gets locked. The game freezes but I have access to my task bar. I can run task manager, start menu, run any other program. But I can't tab to anything. The frozen screen locks my viewing anything but the taskbar, so I can't get to task manager to shut the game down. When you mouse over the frozen game I can hit the x on the little picture that pops up on the taskbar, but it doesn't do anything. Right click close window doesn't work either. I tried everything I can think of, all the controls (windows d, alt tab, shift tab, etc.) I fix it by signing out and signing back in but that is a huge pain and slow.
I tried doing an internet search but I am getting nothing, probably because I don't know the right language/terms to get good results. Anyone else have this issue or know of a fix?
