Hello Mothtears and welcome to the ArtRage forums
I must confess I don’t often record my paintings but on those occasions I have done so I don’t remember seeing the problem you are having at the moment.
And I tried for a couple of hours this morning trying and still no issues for me.

I would suggest contacting Ambient Design directly about your problem.
Give as much detail as you can, i.e; Operating system and OS version, ArtRage version, etc… etc…
You can contact them via the web support page here: https://www.artrage.com/get-support/
Or via email at: [email protected]
I really hope you can get this sorted soon,
