I can't find exactly what the cause of it is all I know is when I use a profile in its own directory then start it up after the first time using that profile it runs into problems taking screenshots, all the photos are blank as if they were transparent but the color are pitch black. I have to try login out and in to the profile and sometimes even the user account to get the screenshots to work most of the time it lets you just change profiles and it works, I have tried it with mods or without them, without resource packs and anything that is not just the base game files, also my friend is having the same problem with his windows 7 computer so Its a bug in the game its self or a launcher problem, its a pain in the neck to work with because I need to take screen shots for thumbnails for my videos and it's hard to do that when there is no output, I have tried messing around with the game settings and nothing helps.

Please for the love of god fix this problem ASAP it's driving me nuts, and there is no help online for it so I have to put up with it in till its dealt with.
