This has happened since I got Minecraft and it's really annoying. A friend told me it's happened since 1.7, and I've played since 1.7.3, Dec 7th of 2013.

It's annoying because I have 1 fps in windowed mode and crashes every 32 seconds in full screen.

I'm not sure if it is my computer or Minecraft.

The 1 fps isn't a bug it's my computer trying to do 20 bagillion things at once.
