Created attachment 193230 [details] webp file with white background instead of transparent background I have created a slide with a transparent background. When I export the slide in png, the png file has a transparent background. But when I export the file in webp, the webp file has a white background. It seems the webp format does not support transparency. I enclose a sample webp file. I am using LibreOffice version 24.2.2.1

*** Bug 160588 has been marked as a duplicate of this bug. ***
Just a note... Bug #160588 was marked as a duplicate of this bug, but bug #160588 describes TWO problems, only one of which duplicates this bug (WEBP with white background instead of transparent). So in order not to lose track of the OTHER problem, I'm reproducing it here. My apologies if these are somehow actually the same bug - if so ignore this comment. The OTHER bug is that text in an PNG export loses its color (i.e., becomes transparent) when "Include transparency" is checked, but when "Include transparency" is not checked. 1. Open bug-example.odg in Draw 2. Export -> PNG -> Include transparency 3. [BUG] Notice text in image is missing color -> see png-with-transparency.png See bug #160588 for the test case.
