M-x calendar 3. M-: (setq o (make-overlay 1 2)) 4. M-: (overlay-put o 'face 'font-lock-warning-face) 5. Use C-n to move point to date in the last line of calendar Symptoms: When the point moves to the last line of the calendar in step 5., the calendar buffer scrolls down, so that the top part of the calendar scrolls off the top of the window and can't be seen. This scrolling bug doesn't occur if a calendar buffer is displayed normally, without creating any overlays (i.e. skipping steps 3. and 4. above). Indeed, skipping just step 4. is sufficient to avoid triggering the scrolling bug. So it looks like the bug is triggered by the presence of an overlay with non-null 'face property in the calendar buffer. (One futher point that might be useful to note: the bug is *not* triggered by zero-length overlays.) The above steps are a minimal sequence needed to reproduce the bug. In everyday Emacs use, the bug is triggered by date selection via `org-read-date' in org-mode (which uses an overlay with non-null 'face property in the calendar buffer to highlight the current date).
