Mouse 2.4ghz mode makes apps laggy (Suspect polling rate related)

[eduardotanco]

Hello, and first of all, thanks for your help!

There is a bug in all MacOS applications where, if the mouse you are using is in 2.4GHz mode, the applications become very laggy when performing certain actions, such as duplicating an object by dragging.

I suspect this might be related to the mouse's polling rate. I use a Razer Basilisk V3 Hyperspeed with a polling rate of 1000Hz.

When using the same mouse in Bluetooth mode, the applications work normally.

I’m attaching videos of the issue below. Also, as you can see, the mouse pointer itself remains smooth at all times.

Steps to reproduce the issue:

1. Connect a mouse via a dongle with a high polling rate.
2. Select a large number of objects in Affinity Designer.
3. Duplicate them by holding CMD and dragging.

Could you fix this issue? The mouse feels much smoother and more precise with the 2.4GHz dongle, and I’d really like to use it that way.
