I have a raspberry pi 3b+ with raspbian. I have a 3.5 inch resistive touch lcd plugged into the gpio pins. The other day I was about to go on the internet and my applications on my desktop shifted to the right. There is a white border on the left. I can slide windows over if I open one but if I hit max it only goes on the actual desktop which shifted about half an inch over. How do I get rid of the border. Is it something corrupted in the os or lcd drivers. Thanks in advance.
