Recently when i go into full screen on youtube or any video player, my task bar will pop up for a second then disappear again, this happens every 3-5 minutes and is fairly irritating. I've tried many different methods such as trying to disable officebackgroundtaskhandler, but i could not find it so i assume i don't have it. I also tried unplugging my mouse and keyboard in case they where bugging it out however it kept popping up anyway. Any fix would be greatly appreciated. I am currently using windows 10, if that helps.
