I created a master slide which has a symbol shape (puzzle) with 80% transparency in the background. When I export the presentation to PNG files, the transparent object is not visible in the PNG file.
Steps to Reproduce:
1. Create new presentation
2. Open Master view
3. Add symbol shape (e. g. puzzle)
4. Set the area transparency to 50%
5. Close Master view
6. Select File → "Export…"
7. Set export format to "PNG"
8. In PNG options, make sure "Save transparency" is checked
9. Click "OK"
- Image filter not found
- General input/output error
Slides are exported to PNG, no error message

This is already in oldest of Linux 6.3 repo, but not yet in newest of 50max repo.
I bisected it with win32-6.2 bisect repo and got a follow sha:

I had the same experience with bug 123973 but transparency has nothing to do with it.
Any item placed on the master, regardless what the type of object is or any properties the object has or doesn't have, fails to appear when the page is exported to PNG.
