Ah, it seems to be related to OpenGL. I am not sure if it's related to my video card, or in kdenlive itself, but when I switched kdenlive to not using OpenGL, it started working fine. ie: no slowdowns when dragging the cursor in the preview window.

Yes, the current openGL display in Kdenlive is really poorly designed and completely inefficient. This will change when the refactoring branch is merged.
