I noticed that usually after playing Minesweeper for more than 10 minutes the app starts to slow down severely and I checked in the task manager which suggests that the minesweeper app is using over 400M of memory! Why would a tiny game like this eat so much memory? And why would it slow down nonetheless even if I have 6G of memory? Is that an execution efficiency problem of the app itself or is it a bug that leaks memory? Thoughts? Thanks!
