A user reported in March 2026 that PNG export crops their map. It has never been on the board, and it is one of only two issues the community raises unprompted (the other is non-macOS performance).
Not reproduced locally, and it needs the reporter's actual .ana file - the shape of the bug is almost certainly bounds computation on some specific scene rather than something that shows up on a demo map.
Where to look:
lib/rendering/export/export_bounds.dart computes the exported region
test/export_bounds_canvas_objects_test.dart covers canvas objects contributing to bounds, which is the most likely omission - a label, decorated box or reference image sitting outside the track bounding box
test/png_export_banding_test.dart covers the banded writer, so a band-offset error would already be caught; a wrong overall bounds would not be
First step is getting the file off the reporter, not guessing. Filed so the report stops living only in a Discord thread.
