Using VMware Workstation 10 on Windows 8.1 I’ve got a strange issue on mouse handling the mouse with strange behaview, like delayed click, area selection (when not required), click on the wrong points, … making the Workstation console completly unusable. Keyboard was working fine in the console and also the mouse in the host OS or in the guest OS when connected with RDP.

The issue was not related on the type of the guest OS (same issue on Windows 7, Windows 8 or Windows Server 2012 R2) and was not related to Workstation Patches (up to date) or VMware Tools in the guest (also up to date).

Issue appear when I was using an external video with a HDMI to VGA adapter and how Windows 8.1 handle DPI scaling.

Solution is quite easy and not related to Workstation: just click on the vmware.exe or on the Workstation shortcut and edit the related settings.

In the “Compatibility” tab just choose  “Disable display scaling on high DPI Settings”. To apply this setting just close and re-open the VMware Workstation.

In the Italian version of Workstation this is the related screenshot:
