[kdenlive] Positioning cursor is slow on high resolution videos

[Pascal Fleury]

Hey Nicolas,

That's interesting, because I thought this was fixed in that version. At
least I think I am using the same version (not at home at the moment).
I also have 1080p material, and had faced the issue I described earlier.
Maybe someone else on the list has an idea ?
