I had a suspicion that a plugin could be causing the problem. Sure enough the todo.py plugin causes the significant lack of visual updates. Even with all plugins disable traversing the list using Up/Down-arrow is still a little choppy but much much better. It is only the todo.py plugin which causes the significant lag in visual updating in the tree, however.
That said, there is still visual lag when holding down Ctrl+Up or Ctrl+Down in the body which moves a line of text. That may be a whole other bug/issue. Can somebody confirm if they're seeing this behavior? On Friday, May 29, 2015 at 6:22:30 AM UTC-4, john lunzer wrote: > > It may not be enough to say that Leo has no control over it.
