The colours are wrong as shown in attachment 151668 [details]
This happens only with gtk3 and kf5. Windows works fine.

The problem is not displayed in slideshow, but it's reproducible after closing it
These are animated gifs, might be a duplicate of an existing gif/animated gif bug
It works correct in gen and qt5, but is broken in kf5 and gtk3, which IMHO looks like the cairo canvas bug, as it also works correctly in Impress edit mode.
I CAN reproduce in LibreOffice 126.96.36.199 with kde5 backend in openSUSE Leap 15.1 with KDE Plasma 5.12.8 + Qt 5.9.7 + KF 5.55.
