I believe the colors being sent to the screen were affecting it. Looking at my desktop, the lines were not on the screen. They used to be in 3.14, though, even on the desktop. But, with this glitch they were not. I opened Libreoffice, with mainly white pixels on the left side, flipped the screen 180 degrees, and...turning off the on HDMI, or whatever it does to the display when it flipped, fixed it, and now it's back to normal. But, like I said, I would wager the glitch was caused by pixel colors, or maybe colors were looked at as commands and the pixel clock frequency is a tad off. I'm not 100% sure on any of it, just saying what fixed it for me so if it's looked in to, it can help. If I could make a new bug report just for that, I will. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
