Random purple lines on the display
Every now and again I'll get thick purple lines covering the entire screen. The lines start happening randomly, but once they start, they continue to come on and off every ~3 seconds.
Closing the lid for several minutes makes the problem temporarily go away.
Applying pressure to the front of the display or just shaking the darn thing also temporarily fixes it. I've only just recently started getting physical with the machine, so you can rule out that I've made the problem worse.
The problem used to go away for a few days. But now I only get about a few more minutes of relief. I'll attach a screenshot showing also a second problem that I've lived with regarding the screen. There are very thin, almost invisible horizontal black lines on the whole display.
They have been permanently there for a year now. One day I was watching a video on the browser, the computer got really hot, there was a quick flicker, the black thin lines showed up and things haven't been the same since. The thick purple lines started to show up some time later.
Also, the underside of the MBP, near the display gets unusually hot no matter what I'm doing.
