Do you have smooth scroll enabled in System Preferences → Appearance?

If so, disable it at least for TextMate by quit’ing it and running this in Terminal:

    defaults write com.macromates.textmate AppleScrollAnimationEnabled -bool NO

There is a problem with the heuristic Apple uses for this smooth scroll where the target rectangle TextMate asks AppKit to scroll to is “augmented”, leading to this seemingly random behavior.
