@jayeff Just wanted to follow up on this. Back on March 26, I was informed my service provider was doing updates in my area so I would be without my services during that time. Once they finished, my glitching/pixel issues have seemingly gone away and are not an issue anymore. So in the end, it didn't seem to be anything wrong on my end. I just wanted to say thank you for all your help these past few months and for your patience in trying to help me!
