Description: Mint 21.1 by default installs LibreOffice with libreoffice-gtk3 1:7.3.7-0ubuntu0.22. As long as this package is present, IMPRESS slideshows MPEG4 and AVI videos in left-justified monochrome, even though the default Celluloid viewer and VLC display them perfectly. Removing the subject package changes Impress' UI’s as expected, then mpeg4 and avi videos in the same presentation SLIDESHOW display and play properly. Steps to Reproduce: 1.Install libreoffice-gtk3 1:7.3.7-0ubuntu0.22 if not already present 2.Attempt slideshow of a presentation with an imported mpeg4 or avi video 3.Remove the subject package with APT, etc. 4.Restart Impress, load presentation with video, and repeat Actual Results: While libreoffice-gtk3 1:7.3.7-0ubuntu0.22 is present, IMPRESS slideshows imported MPEG4 and AVI videos in left-justified monochrome, sometimes over a color still of the first frame as shown prior to starting the SLIDESHOW. Expected Results: After the subject package is removed and Impress is restarted, the same presentation file with imported videos slideshows perfectly.

Thank you, Dave. LO 7.3 and 7.4 won't see further bugfix versions. Can you please test again with LO 7.5? https://www.libreoffice.org/download/download-libreoffice/ It can be installed alongside your current version.
Removed LO v7.3.7.2 in its entirety, including package libreoffice-gtk3 1:7.3.7-0ubunto0.22 Downloaded and installed LO 7.5.4.2-2. Ran Impress, confirmed version was 7.5.4.2 Loaded same presentation and observed the identical bug in screenshow Noted UI render:default;VCL:gtk3, though libreoffice-gtk3 was no longer a package that could be removed in order to resolve the bug Removed LO v7.3.7.2 and reinstalled v7.3.7.2 Removed libreoffice-gtk3 to restore usable screenshow.

Thanks for the info and file, Dave. At first I could not play the video in Impress, only scrub it, but the same would happen with the default media player on GNOME with the extracted file, which used the H.264 (High Profile) codec. I then installed a bunch of packages, hoping I was missing a decoder, including: libavcodec-extra gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav ubuntu-restricted-extras libdvdnav4 libdvdread7 libdvd-pkg (some of them I already had) After a reboot, the video plays without a problem, in and outside of LibreOffice. Can you see what media decoders you might be missing for Linux Mint, given that LO relies on the system's libraries for media? VLC bundles decoders, so maybe also test playing the same video with the default Mint media player to see if the same issue is seen there.
All of the codecs you named were already present on my system except ubuntu-restricted-extras and libdvd-pkg. Installing those two had no effect on Impress 7.5 after reboots. libdvdread7 is not available in the Mint sources. The test video I submitted plays flawlessly in VLC and Mint's default Celluloid front end for MPV. GNOME's totem viewer, however, displays only the narrow, monochrome video I described previously including after the two above codecs were installed. If the slideshow of the test presentation I submitted is advanced into Slide 2, Impress 7.5 superimposes the narrow monochrome video over a static color frame video. It must have distracted me from noting the latter's being static. If the first blank slide is removed so the slideshow begins with the inserted video, only the narrow monochrome is displayed. I opened a new presentation in Impress 7.5 and attempted to insert other .avi and .mp4 videos. If the video was over 4MB or so, doing so caused Impress 7.5 to display a white slideshow or crash. All played perfectly in VLC or Celluloid. Totem displayed a 2.3MB one in narrow monochrome, reported the others which were larger as not existing.
Right, so if the issue is also visible in Totem, we'll have to call this bug "not our bug" and figure out why the video can't be decoded properly on your system. You can try playing the video from the command line with: totem video.avi ... and see if it outputs anything interesting. Totem's "could not be found" issue seems to be known: https://askubuntu.com/questions/1406254/after-installing-ubuntu-22-04-the-default-video-player-is-unable-to-play-any-vi You can see if uninstalling this package helps: sudo apt remove gstreamer1.0-vaapi Further issues with that might be best discussed on a Linux Mint forum? Regarding LO 7.5 crashing: It would be great if you could report the issue in a separate report, attaching the video sample. Do you get a crash report when restarting LO? If so, please link to it too. Thanks for your help figuring it all out!
