XPS 15- 9550 Wireless Mouse Lagging, But Trackpad is Fine (FIX)

Hey guys,

I'm running a 9550 with an I7, 16gb memory, and an SSD with the 1080p screen (Windows 10)

I wanted to add this in here since I googled and reddited for solutions but nothing seemed to work.

After installing the latest Bios update, I had a really strange problem where my mouse would lag like crazy, and skip around whenever I tried to highlight in order to copy/cut sections of text.

Here's what worked for me: Updating the driver for my bluetooth.

In case you don't know how to go about doing this:

In your Search, type in Device Manager.

From the list shown in Device Manager, select bluetooth, then select "Dell Wireless 1830 Bluetooth 4.1 LE"

Right click and update the driver.

There are multiple issues that cause the glitching, but this was the one that solved my particular problem.
