I've had this problem for a while now and I've noticed that it isn't just showing up on the minecraft launcher. It shows up on any kind of .jar file or .JNLP files, pretty much anything that runs off of Java. It's pretty hard to explain so I figured I'd just record a video so you guys could see it and perhaps suggest some solutions. I don't care if you experience this problem too. If you do, just keep an eye on this thread. Please only reply if you think you can help. Also, what you will see in the video is EXACTLY what I am seeing, it isn't some bug with my recording software.
Disappearing text boxes bug or something
