SUMMARY
**
When previewing timeline, playback pauses briefly at each new clip
***
As Play-head passes each clip on the timeline, playback on the project monitor
briefly pauses. This also occurs during a dissolve/wipe transition. This does
not happen with previous version before 21.12.0. Occurs with both Appimage and
Flatpak. Video clips used in project are 1080p/ 50 fps/ .mts
STEPS TO REPRODUCE
1. Load a project
2. Play through timeline until clip changes
3. Also occurs when clips have been added to a new project
OBSERVED RESULT
Preview plays smoothly until next clip or transition in timeline is reached,
play back pauses briefly ( <1s) . Playback sometimes continues to play back at
a low frame rate
EXPECTED RESULT
Smoothly cut or transition to next clip and continue to play smoothly.
