I have several grids in my app, but I've noticed that when I set a height on a grid (to show the scroll bar and make the grid vertically fill its container), the header row seems offset.
Here's a grid with no height;
And with Height="70vh" set on the same grid;
The headers are slightly offset - on other grids, it also appears that the more rows, the more offset the headers become.
Anyone have any ideas what might be causing this? Ive not found anything that even plausibly could be causing it in my code.
