Macbook screen freezes when I move my external mouse I recently updated to macOS Big Sur, and I wanted to use my external mouse for work and gaming. I plugged in my mouse using a USB dongle, but every time I moved the mouse, the screen would freeze. In the games that I was playing, if I didn't move my mouse, I was getting around 80 FPS but as soon as I started moving my mouse, my frames would drop significantly, to around 15 FPS,  but they would improve as soon as I stopped moving my mouse. This issue doesn't happen at all when I use the trackpad. Is there any fix for this issue?
Laptop Specs:

Intel HD Graphics 5300 1536 MB
I have been experiencing a similar problem with my Logitech G Pro Wireless mouse plugged into an Anker hub. I believe I have resolved my issue by changing the mouse's polling rate from 1000 to 250 in the G Hub software for the mouse. You may try changing the polling rate, if your mouse supports it, and see if that helps with your issue.
