How can I fix my shaky mouse when presenting my work computer on Microsoft Teams

Solution 1:

As first try, you could in Teams Settings, temporarily turn on "Disable GPU hardware acceleration (requires restarting Teams)". Restart Teams to see if it makes any difference. Undo if it doesn't.

Another try comes from the Ask Woody article
Carboni: Jittery mouse when controlling Win10 version 1903 via RDP? There’s a solution:

Microsoft has enabled (and made default) the use of a second driver model on the system being controlled: The WDDM model. Up to now RDP has run off the XDDM display driver model, which is apparently better optimized for an interface that takes a noticeable amount of time to update a mouse cursor given mouse position input. Remote connections take milliseconds, if not tens or hundreds of milliseconds. Therein lies the problem.

The advice in the article is:

• Run the Local Group Policy Editor (gpedit.msc)

• Navigate to:
  Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Remote Session Environment

• Set the "Use WDDM graphics display driver for Remote Desktop Connections" policy to Disabled

• Restart RDP.
