What is your operating system?
What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
Can you repeat the problem? If so, what are the steps?
When you move something on the timeline, it immediately snaps past the end of the closest item instead of attaching to it. Visually it’s a jerk of the selected fragment jumping a few frames and cutting into the previous segment.
This usually happens when I split a video file on a track, then add pictures on the same track and audio on a separate audio track.
The workaround is to disable snap and position the piece manually.
