Bug ID: 166646
Summary: IMPRESS, SLIDESHOW, Display glitches when playing MP4
media video files with subtitles
Product: LibreOffice
Version: 24.2.7.2 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: minor
Priority: medium
Component: Impress
Assignee: [email protected]
Reporter: [email protected]
Description:
Impress presentations that contain MP4 video files with subtitles show severe
display glitches when in presentation mode. Removal of the subtitles from the
video fixes the problem, and the video now plays normally.
Note that this is for Linux distros with GTK based desktops only; QT based
desktops have different form of display glitches that will be the subject of a
separate bug report.
Steps to Reproduce:
1. Create, or download, an MP4 video with subtitles (codec: tx3g)
2. Create an empty simple, two slide, presentation.
3. Add simple text title to first slide.
4. Add video file to second slide.
5. Save file.
6. Play presentation, with presenter console option selected.
Actual Results:
When you get to slide 2, the video plays with full screen glitches every few
seconds. The playback frame rate is also slower than the original file.
Expected Results:
Play the video normally without glitching.
Reproducible: Always
User Profile Reset: No

This issue only affects GTK based desktops; QT based desktops show a different
form of display glitch which will be the subject of a separate bug report.
This display glitch is repeatable across three different machines, both desktop
and laptop, from two different manufacturers: Lenovo and HP.
I have also found the same display problem on the latest (Flatpak) version of
LO: 25.2.3.2
