Transformed Texture strange behaviour

Hi,
I try to understand the transformed texture node… but I am facing a strange behaviour which needs to close an open the project again.

  • Create a new transformed texture
  • Import a simple “image.jpg” file
  • In the transformed Texture properties, choose “image.jpg” as “texture”
  • Changing the positions/Scale/Rotation values in the “Transformed texture” numbers fields works.
  • As soon as I hit the Scale(X) or Rotate© buttons tools, the image becomes white in the preview, and the parameters from the Transformed Texture doesn’t work anymore… Need to quit and do it again from step 4.

Thanks.
