Problem Description
I encountered a significant lag issue when using LibreOffice Impress on NixOS, even after installing all required GStreamer dependencies. The problem occurs when switching to a slide that contains an embedded video:
- Each time I switch to a slide with a video, Impress becomes temporarily unresponsive, with the window showing “Not Responding”.
- This freezing period seems related to video loading or decoding, although no error messages appear when launching Impress from the command line.
- Impress eventually recovers and resumes functionality, but the temporary freeze greatly affects usability and user experience during presentations.
Expected Behavior
I expect smooth and responsive transitions between slides, even those containing embedded video, without noticeable lag or temporary application freezes.
