Thank you for reporting these issues.
If you have high resolution display, for example 4k or 2k, I'd recommend to lower resolution to for example 1920x1080. You can do this from the settings (gear icon) > visuals, under "FOV"
The white pixelated circle of light is caused by the motion blur setting. Also settings > visuals
As for the controller - what controller do you have? Game has universal gamepad support, so controllers should work - but there might be issues with specific controllers. I have tested with a PS5 controller on my MacBook.
