[2022] Potential fix for mouse / trackpad issues on Singularity

Hi,

We have a potential fix now on Singularity for the reported problem with the lagging mouse / trackpad, especially with dragging windows.
As I could never reproduce this on any of my test machines, it would be great, if you could take a look on Singularity and see if this issue is indeed fixed.

Tagging a few, who reported this issue recently: @OldGuyMonty , @Zed_s_Motorcycle

Thanks for you help!

This fix has been released to TQ today.
