Borders can overhang 1 px from the corresponding cells. The issue is reproducible only on some zoom levels, and is most probably related to WPF layout rounding. The issue is mostly visible when borders are missing. On different zoom levels, different borders are hanging.
This behavior was originally reported over 11 years ago and has not received significant demand or follow-up from the community since then. This is why we plan to prioritize more impactful and widely requested improvements.
If this limitation is still affecting your scenario, please share additional context or use cases. This will help us better assess the severity and reconsider prioritization in the future. Thank you!
