I have this weird lag that I never encounter on playing Minecraft. Whenever I didn't move the mouse, the fps can get over to 200 FPS, but once I move the mouse, the FPS drops immediately to around 1-10 FPS, soon when I stop moving the mouse it goes back to normal. But, if I click the mouse while moving, there is no lag. I know that this is a duplicate issue, but it seems that I haven't seen any solution from previous issues. Below is the specification of my laptop :
Model : Macbook Pro (16-Inch, 2019)
Processor : 2,3 GHz 8-Core Intel Core i9
Memory : 64GB 2667 MHz DDR4
Graphics : AMD Radeon Pro 5500M 8 GB
