[vtkusers] vtkusers Digest, Vol 151, Issue 35

[Sankhesh Jhaveri]

Richard,

There isn't a bug filed yet for the mask update issue. Please feel free to
do so.

Although, Michal has a patch for the mask update issue already. Michal,
would you be able to create a merge request with your patch? Or should
Alvaro do it?

We can look into the performance woes that Michal experiences, as a
separate issue.

Thanks,
Sankhesh
