I’m on the latest version of Shotcut Windows 64-bit.
When editing a project that has many clips in it, often simply moving one of them causes major freezing and sometimes crashing. The longer the video(or more clips the video has?) the worse it gets.
If anyone has a potential explanation or even a fix that would be great.

Shotcut - Windows 10 - presumably all versions
Steps to reproduce:
1.) Creat… e a project with several video tracks and so many clips that moving one doesn't seem "instantaneous" - even on a very fast machine this is not more than a few hundred (the project from issue #1029 may serve as an example)
2.) Drag an arbitrary clip from the timeline within its track and WITHOUT ever leaving said track - this is your normal operation speed for reference
3.) Drag the same clip but to another track - operation takes around 100 times longer (much longer than select, Ctrl+C, position playhead, Ctrl+B, Del of the original clip would take), at least several seconds
4.) Surprisingly this also happens if you just briefly leave the orignal track while dragging, even when releasing the clip on its original track but at a different position - the operation takes a very long time

If you really want to understand why in more depth, you need to study the source code. And while there maybe you want to help out and improve it.
Cut & Paste, rather than Drag, does not have this problem.
