After several tries (command-down-arrow again and again) we might get to the end. This was always the case but now it is worse.

This was always the case, but the difference from the previous version is the actual selected line appears but then jumps away out of view and we have to command-J again, and possibly again, to get the window to steady itself.

I have to pick the heading _again_ to see it. Everything I do is taking twice as long as it should because I have to do everything twice like this. This is all completely new (to me) in this release; keep in mind that I have not updated since the last major release so I don't know exactly when all this came along.

Thanks for the specific examples. I was able to reproduce the example
shown in the screencast with the latest release and in doesn't happen
(or at least not as bad) in 2.0-rc10, which I believe was the last
release. There were quite a few nightly builds in between, but I will
try to determine which release actually introduced this change to
narrow the scope.

Actions like scrolling or global find result in long delays or large apparently blank areas. It would be nice if when I say "open this file" TextMate 2 would well and truly just _open_ it. m.
