display glitch

    Why are my videos doing this? Windows 11

    I have a Dell Latitude 5550 , with Windows 11. When I play video it sometimes starts out fine but the picture starts acting crazy. I am attaching a picture of a video and what it looks like. Any idea why or what to do to fix this??
  2. Windows 8 Switching to a window reveals black cover on parts

    Whenever I switch from the desktop to my browser and some other applications as well, I get this: (Black boxes cover up some of the application) and I have to either repeat the switch over multiple times or I have to click around the page to get all the boxes to go away.
