VLC pixelation issues are coming when using the popular media player.
The video plays perfectly at first, but if you switch to full-screen mode, the video becomes pixelated or VLC player gets pixels flashing. This issue occurs even if your video card drivers are up to date.
You’d have thought that the VLC pixelated MP4/MKV is from the video, but it’s not. This is because the video plays fine in full screen on other players, such as Windows Media Player.
The following solutions have fixed the VLC pixelation issues for other users.
What to do if the VLC media player keeps pixelating videos?
