Description sebastian.severin 2019-03-17 22:10:59 UTC
Description:
I insert vector graphics (svg file format) in a presentation.

Minor problem: In normal edit mode it looks good but on OX X some transparency effects are incorrectly shown in comparison to the presentation in Firefox/Safari.

Main problem: When I start the presentation mode the vector graphics are displayed incorrectly (color, transparency and aliasing). It does not matter if OpenGL is enabled or not. The effect also occurs on the start dialog where I can choose resent opened files. This problem also occurs on Debian Linux with and without OpenGL enabled (4.19.0-1-amd64 #1 SMP Debian 4.19.13-1 (2018-12-30) x86_64 GNU/Linux; Mesa 18.2.8m DRI Intel(R) HD Graphics 5500).

I tested it also with Libre Office Versions 6.1, 6.0 and 5.1. And I tested it with OS X on a MacBook with Intel GPU and a second MacBook with NVidia GPU and I get the same result.





Steps to Reproduce:
1. create a new empty presentation
2. insert a vector graphic (svg file format) per drag and drop
3. start the presentation mode

Actual Results:
Vector graphics are displayed incorrectly (color, transparency and aliasing) in presentation mode. On OX X some transparency effects are incorrectly shown in comparison to the presentation in Firefox/Safari.

Expected Results:
Vector graphics in presentation mode looks like in edit mode respectively the presentation in Firefox/Safari.


Reproducible: Always


User Profile Reset: No



Additional Info:
Demo presentation, used svg files and screenshots (from linux and OS X) are attached. Vector graphics are from faenza icon pack.

I use a germen language version, I hope the used terms are correct.

Confirmed (most prominent on Mac, but visible on all platforms when h/w accel is switched off).

Dear sebastian.severin,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
 
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team
