The problem is with how TextMate does lazy layout, it does an initial 
heuristic (fast) layout and uses that for scroll positions and then only 
does the real (slow) layout when needing to display the text, which can 
“push things around” (and cause the previous correct scroll position 
to now be incorrect).

Long-term I hope to improve this, but it’s non-trivial because laying 
out text is surprisingly slow.
