No Mouse cursor with 8.1 (and workaround)

[Tue-Tue]

It works. Mouse is still laggy but adding this registry key solves the cursor visibility problem.

Thanks a lot, Alban

I would like to gauge the impact.

Key: HKEY_LOCAL_MACHINE\SOFTWARE\DisplayLink\Core
Value: LowLatencyMouseCursor
Data: false
Data type: REG_SZ

Kind regards,

Thank you for testing this.
This key simply disabled the work done to change the way the mouse cursor was handled.

I am very sorry this was not developed properly. We did test it internally before we released the change, and I don't yet know why this doesn't work for some machines when we did not have the missing cursor on any internal machine we tried on.

Would you please be able to generate ZIP file of your logs with our Customer Support Tool as described in the last link in my forum post signature?
We need to reproduce the issue to understand what is going wrong and selecting a machin as close to yours as possible will be key.

Kind regards,
Alban

Tue-Tue,

Thank you for the logs. It has helped us select the machine to setup the reproduction.
Once I have an update from the engineering team, I will share it here.

Kind regards,

Hello,

Root cause has been found.
Some graphics cards put the wrong depth (they set it to 0) on the surface.
Instead of simply using the depth value given, we will gather it from somewhere else if we're told it's 0.
We're implementing the change and will have to test it.

Kind regards,
Alban

Hello,

The fix for that is now available from 8.2 Beta onwards.

Hi,

Just a quick word of thanks for resolving the issue I've had with my "invisible" cursor in the extended monitor. I have the Diamond Multimedia MDS3900, as well as the Plugable UD3900. I could never get my cursor to display in the MDS3900 until I installed the 8.2 beta.

Thanks a bunch!
