Occasionally when switching from full screen to windowed, and once just playing the game windowed, Minecraft will lock the entire MacBook Pro.

The machine will be briefly responsive for around 2 seconds every few minutes, other than that it's frozen. The system log has repeated entries for:

kernel[0]: NVDA(OpenGL): Channel timeout!

Usually a forced power off is the only solution.

This has only started happening in the last month or two. This machine is used heavily, Minecraft is the only app causing this.

Sounds identical to MC-4446 and maybe MC-10968.
