Blurry Previews in Viewer after using Keystone

Hi everybody,

after Update of Capture One my Previews and my Picture in te Viewer get blurry after I used the Keystone Tool.

If the Picture was enlarged to 50% or 100% the Picture is already sharp.

I'am working on an Win11 Workstation.

I need immediate support, because that's not the way to work with it.

Best regards 

 Frank
