Hello! I've been having some concern with my Gateway NV59C26u laptop. Sometimes when I wake the screen, there will be artifacts on the screen. Not always, but sometimes. It never happens otherwise. Only when the screen has been turned off and then back on without shutting down the machine. Any suggestions as to why this could be? It's one of those Intel HD Graphics cards that come with the first gen Core i3. The drivers are up to date. Edit: A couple things I forgot to mention. This problem used to only occur when I locked the screen and then came back and it'd be on the login screen. But it moved to the desktop recently. And when I move windows over the artifacts, the covered parts will "erase" until the next time.
