Version info
Do you save your file on a local disk or on a network? Indeed, renaming the file into an zip and try to unzip it, I get: End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. sorry wrong bugtracker, forget my last comment. Please attach an example document.

Outcome of export selection to png
Created attachment 191197 [details]
Impress slide with large margins and two drawing objects to export to PNG
Export to PNG with transparency set exports only the parts of the slide inside the margins but the dimensions of the slide are set as the dimensions of the PNG resulting in distortion of the resulting PNG. Also applies to Draw. Attachment created as described:
1. Open a new Impress blank slide at Screen 16:9
2. Set the right and left margins to 10 cm, leaving an 8cm area for content
3. Draw a 5.00 cm diameter circle, blue fill, inside the margins
4. Copy the circle to overlap a margin and area fill circle to green
5. Click File > Export and set PNG, ensure Transparency is ticked, leave other settings
RESULT: Exported PNG has proportions of full page but only the content within the margins are included. The blue circle is distorted to a flat ellipse and green circle is cropped, see slide 2
6. Instead, click File > Export and set PNG, ensure Transparency is NOT ticked, leave other settings
RESULT: Exported PNG has proportions of full page and all content is complete and undistorted, see slide 3
