Do you get a skewed image when you copy it from LuxRender to the clipboard and then into a image editing program like Photoshop?

 

Usually.  I've kind of given up on that.

Rarely. I think it has to do with which app you use to copy the clipboard in. Maybe some slight incompatibility, or a more or less strict implementation of clipboard norms?
Anyway, I have found that XnView (free image viewer/converter) usually has no problems with Lux clipboard exports, so I use that.
