Discovered odd behaviour today with a DesktopListbox with checkboxes in its cells, under Linux (mint and separately on a Pi). As the listbox is scrolled and the row disappears off the bottom the checkboxes stay visible as they move over the bottom edge of the listbox; they stay visible entirely until they are entirely out of the lisbox. Then they vanish. Doesn’t happen with macOS/Win.
Issue 74580.
