Description Tamás Zolnai 2018-09-22 15:52:29 UTC

When open Media Player in Impress on Windows and moving the slider on the dialog it's rendering is wierd on Windows. All the earlier states of the slide is displayed and so the slider handle is displayed more time (see the screenshot).

2. Open Tools -> Media Player
3. Open a file (see the attached one)
4. Move the main slider forward and backward

Actual Results:
Slider handle displayed more times (see screenshot)

Always only one slider handle should be displayed.


Reproducible: Always

Let's convert this one an easy hack
The media player code is here:
avmedia/source/framework/MediaControlBase.cxx

MediaControlBase::UpdateTimeSlider() method can be a good start.

This is not an easy hack anymore. Rendering is a tricky topic on LO.
