When I move between tabs (either by clicking on tab or using Option-Command left, right arrows) sometimes the page scrolls up by 1 to 3-4 lines each time. But once it does this scrolling then it will do so every time I come back to that tab.

The problem is that it stores a buffer offset as the “first character” but this may visually change due to delayed softwrap calculation.

It’s not a new issue: Once I get around to overhaul the text layout/rendering code, I expect to address this and other related issues.
