This is my first computer with a high DPI screen, so I don’t know if this is related to that.
I don’t get on with track pads and use an external USB mouse, a Logitech M185 as it happens. I’ve used it with my last two computers and it’s great.
On the Eve, about half of the time when I click the mouse pointer moves enough that the click doesn’t register as a click but as a drag. I do use the mouse on uneven surfaces but never had this problem on my last two laptops.
The mouse pointer moves across the screen at just the right speed for me. I know I could slow the pointer down but that would be frustrating.
