Hello everyone. Some days ago i bought a Surface for my mother, everything was fine. However today, my cat stepped on the physical keyboard/cover of the device, and a strange artifact appeared on the left side of the screen. I immediately thought that something might have been broken, but the device didn't take any hit. I mean, it didn't even move, the cat just pressed a few buttons on the keyboard and this thing appeared. It looks like a LOT of semi-trasnparent code lines are running from the top to the bottom of the left side of the screen, so before sending the whole thing to the repairing service, i wondered if anyone here knows if it's some kind of shortcut or key combination that actually displays that thing. Sorry for my english and thanks in advance for the help.
