Description Hadmut Danisch 2018-07-17 15:19:58 UTC
Description:
Hi, 
when exporting a slide as a PNG (Export... menu then choose png) the shadows of texts with the shadow property get rendered as transparent, not as black. No matter whether keep transparency is selected or not.

Steps to Reproduce:
1. Create some slide with a huge headline
2. Turn the text shadows on for that text
3. Export as png
4. watch the png file with a file viewer capable of displaying transparency (as checkerboard pattern), e.g. eog

Actual Results:
Text shadows transparent

Expected Results:
Text shadows black (as on the presentation)


Reproducible: Always

Seems to be fixed in 6.1.0.1

Unfortunately I've seen the announcement of the alpha release available for testing just on the bug page _after_ submitting the bug. I would have tested it otherwise before submitting the bug.

No, not really fixed in 6.1.0.1.

When not selecting "Save Transparency" in the PNG dialog, slides look good, but when selecting (whatever this is good for), shadows still become transparent.

I did many tests and first it looked like I could repro, but finally I could not.

Please attach an example file, so the testing will be consistent.
