Sometimes, when I open Minecraft, the buttons will be mostly unresponsive. I have to click multiple times to enter the load screen. Because I don't want to risk messing up my world, I always quit out of Minecraft (after several clicks of the "Quit Game" button) when this happens. When I restart, the problem goes away. I'm attaching a crash report.
Can you provide a video of this happening. If the video is too big for the bug tracker post it on YouTube and put it as Unlisted then post the link here.
