Slow mouse click response

Hey everyone!

I've recently encountered some strange behaviour when using the MX Master 3S on macOS 27.0.1. When I start dragging a file, the left mouse button seems to register with a noticeable delay. As a result, another file may get selected, or the mouse may start selecting multiple files instead of dragging the intended one.

In the video you can see it happening – I click and hold the left button when the pointer is over the file.

The problem disappears after I restart Mac, but returns after a while.

while I haven’t encountered something like this, Apple has fixed various drag related issues on macOS 27.2!

Whoops, somehow missed it, updating as we speak. We'll see it if the problem returns, thanks!
