Spacer tool is too slow in certain sittuations
Simple example dragging a part of the clips in a project: Peek_2021-02-28_15-18
This with thumbnails disabled on all tracks (I was trying to understand if this could be the issue).
[ME] See here as well: https://bugs.kde.org/show_bug.cgi?id=441662
[ME] Here an easy test from the forum (https://discuss.kde.org/t/performance-improvements-are-probably-necessary-when-moving-multiple-selected-items/5150): Add 350 times the same picture to the timeline and try to move all clips or move parts of it with the spacer tool. Kdenlive behaves very laggy.
