Starting with Lightroom Classic 13.5, Panel End Marks will disappear if the side panels are very long. This issue did not occur with 13.4 and earlier.
OS version: macOS Sonoma 14.6.1
Hardware: 14-inch MacBook Pro with M3 Max processor
Steps to reproduce:
- Enable Panel End Marks from Preferences > Interface.
- In any module (Library, Develop, etc.), right-click on any panel and select Collapse All. Note that the Panel End Marks do appear.
- Expand panels until the panel is sufficiently long and requires a notable amount of scrolling to see the bottom. Note that the Panel End Marks no longer appear, and an empty space appears instead.
