What happened?
I've been noticing this while peer-reviewing submissions on Coursera. I load up somebody's program (just noticed it with a Snake implementation), and set the emulator speed to high (screenshot below), and hit run.
The program runs until it's done and then the emulator stops. Fine. But if I hit run again, although the speed slider still looks like it's in the same position, the emulator runs at a crawl compared to the previous speed. It feels like the speed is reset internally but the UI is not updated.
To reproduce: compile and run this snake program. pause the emulator before the snake hits the wall on the right. reset the PC to the start of the program and start again. When I do this, on second running it goes much more slowly. If I pause, then wiggle the slider and put the slider back all the way to the right, the emulator speeds up again.
