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