Created attachment 190194 [details] Sample slide (PPTX) How to reproduce 1. Open sample document. 2. Copy and paste the first slide, i.e., duplicate it. 3. Save under a new name. 4. Open the new file and observe how the dark green background at the top of the second, copy&pasted slide is now black Note: This only happens when saving to PPTX in step 3. Saving to ODP does not reproduce this. Note: It also happens (though not tested as extensively) when the original file is in ODP format. And now the head scratcher: Start with an ODP document with two instances of the original slide, copy those two and paste them, arriving at four instances. Save as PPTX. Voila, #1 is correct, #2 to #4 are black.
