I'm having trouble viewing some videos, mainly those on websites and some youtube videos, though netflix and amazon prime videos look fine. For the videos with issues, they look extremely zoomed in. The rest of the page is not zoomed in, only the video, and thumbnails of videos look...
When watching videos on VLC, WMP, and even anything online, for example YouTube, every 30 to 60 seconds the screen resizes to show the task bar then goes full screen again. This happens over and over for the duration.
Only started a few days ago.
Could it be a virus of some sort?
