Shift+Click the green flag to turn on Turbo Mode
An interesting thing that I noticed is that on the left side, the displayed FPS-es are different. I think what happens here is that the Turbo Mode makes Scratch process multiple frames at once, and the speech bubble is updated after the last subframe, but the variable display is updated after the first subframe. This would also explain why the variable turns into Infinity when I stop the project. Made for https://scratch.mit.edu/discuss/topic/874192/
