Problem with mouse pointer hand with labelw:

When the user has increased the cursor size in the windows settings e.g. set to 3, and I set the mouse pointer for a labelw to 4 - Hand, then the mouse pointer is pixeld:
Attachment 194463
(Irfan View could not capture the correct cursor (arrows instead), so I took a picture)

With other controls the hand is shown correcty.

What's the problem here? how can I fix that?

Thank you
