Sample slide (PPTX)

In edit mode the sample document looks identical in Impress and
PowerPoint - text is rendered in white.

In presentation mode Impress renders that same text as green
(whereas PowerPoint stays with white).

Version: 24.2.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: b5aaf194866c5e416167cb54d37f9f04dabc5375
CPU threads: 8; OS: Linux 6.4; UI render: default; VCL: gtk3
Locale: en-US (en_US.UTF-8); UI: en-US

...back to 6.4 at least.

Example file in presentation mode PP 2016

Seems to be green (for some reason) in my PP 2016 in presentation mode.

Which version of PP do you use?

> Which version of PP do you use?

It's the web version, reporting as Microsoft 365, build 16.0.16816.40510.

(I also asked the colleague who created the original with PowerPoint on 
a Mac for details.)

Reduced (in size and build-ups) sample slide

(In reply to Gabor Kelemen (allotropia) from comment #2)

This got me thinking, so I spent a chunk of time simplifying this
further, notably reducing the dimensions of the slide (which were
enormous).

Also I removed two of the build-up steps.

Does this work for you now?

Interestingly, the two bits of text where I removed the build-up
render white in presentation mode now! Only the one bit where there
still is a build-up renders green.

Still green in the offline versions, also in PP2019.

I see this suspicious part in the markup:

                                                                                <p:tgtEl>

                                                                            </p:cBhvr>
                                                                            <p:to>
                                                                                <a:srgbClr val="30BA78"/>
                                                                            </p:to>
                                                                        </p:animClr>

30BA78 is the green hue we see. How to set this in the UI? Needs more investigation...
