It started to crash and then put my skin PNG on full screen and kept blinking. I had to restart my computer over and over again. In the end I had to wipe my entire laptop clean. It was a brand new gaming laptop it was just bought that day before and the only program on it was Minecraft (C) (R). The only way to repeat this is to hold the following keys in the direct order: hold (Shift, Control, Space Bar) you stager these keys while you click the Play Button On the launcher. Please get this bug fixed. I tried it out on my other 2 year old desktop and it didn't have a problem. The file attached is what I mean b my skin PNG.
