Deformation of PNG file in Lightroom CC

Question

From the Lightroom CC library I choose "Edit in Photoshop CC" and I edit a CR2-file. In Photoshop I save it as PNG-file, in order to keep the transparacy of a part of the picture in other applications.

Bur when I import the PNG-file back in Lightroom, only a part (1/4) of the picture is visible. The rest of it disappeared. When I export that PNG picture to a JPG-file, only the visible part of the picture remained.

When I look up the PNG file outside Lightroom (for example with Finder or Paintshop), I see the complete picture.

What can I do to get the complete PNG file in Lightroom??

You are applying a Crop (red circle) to the LR imported PNG file. Open the Develop module Crop tool and Reset.

As in the separately added picture below.

Lightroom does not support Alpha channels and renders transparent areas in White. Export files will appear the same. A workaround is to create the PNG file format copy in PS after all LR and PS editing have been completed.

Sorry, it appears there is an issue with the way transparent areas are being rendered in the Develop module with 'Use Graphics Processor' enabled. Try setting your LR preferences as below and see if that corrects the transparency rendering. The Library module preview doesn't exhibit this issue because the GPU is only used in the Develop module.

Please post a screen shot of the LR Library module showing that image.
