Hiding liquify tool pointer in Affinity photo

[rectifier]

I need to hide the pointer (central cross with big 1024px tool-size circle round it) while applying the liquify turbulence tool in Affinity photo.  I'd like to be able to drag the tool down the screen from top to bottom, filming as it causes its effect, without seeing the tool pointer/cursor.  
I know pressing space bar turns it into a much smaller hand, but that's still no good and acts as a view tool, pulling the artwork down too.  
I suspect it can't be done, but will be very happy if someone here can prove me wrong.

Hi rectifier,

Welcome to Affinity Forums

There's no option to hide the cursor in Affinity Photo, but you may be able to hide it if the recording software you are using has an option to hide the cursor.
