May I know why do you think spamming keys when opening the program will make it less likely to happen? Perhaps you have an idea what causes the issue?
Yes, the top left is showing how many ticks per second being simulated.
I'm not sure why the cells disappear off the left side of the screen. I haven't encounter the issue you mentioned. I recorded the videos on my computer: https://drive.google.com/drive/folders/1GDncjYbLxKh8OcYmZ7R6h3Cv3pZqUCjc?usp=sha...
The tps will increase if I batch all the jobs together, but it will cause stuttering. As I mentioned in the "possible improvements", using IJob directly for each chunk is likely the solution.
