I am using LO 5.2.2 RC2, and I noticed that in Writer, the vertical ruler disappears is only visible on pages where the cursor is. So if you scroll down or up without changing the cursor position, the vertical ruler disappears.

I see this also in

LibreOffice 3.3.0 
OOO330m19 (Build:6)
tag libreoffice-

so it was there from the start of the LO project.

The problem is the same when scrolling with the mouse from a two-page document upwards to the first page - the ruler only gets displayed once the cursor has been activated on that page.

The bug is still present. The vertical ruler is present at the page where the cursor is, but not at other pages.

This applies to both vertical and horizontal rulers.

Demonstrated with:

0. Open Writer
1. Insert 3 page breaks with Ctrl + Return
2. Use "book view" in the status bar
3. Turn all rulers on in View > Rulers
4. Scroll to the top of the document

Result: visible page has no rulers.

However, I think it qualifies as an enhancement rather than a bug.

Still valid for a recent master build:

Comment 12 R. Bingham 2023-03-24 15:43:48 UTC
I suggest part of this rulers view issue is a user uncertainty in expected behavior. In the View->Normal view (physical page emulation) with rulers enabled:

A) In one model, all emulated physical pages having even a partial appearance in the document pane are expected to be rendered with associated rulers visually adjacent in full or part.

B) In a second model, the existing behavior of only rulers for the active (by cursor placement) page are rendered.

C) Something else.

Let us say I as a user enable rulers in Normal view and the behavior does meet my expectations. Is this a bug or something I just do not understand. Hmmm... review the documentation at 


which is silent on intended ruler view and rendering behavior (other than enable/disable menu choices).

I suggest a documentation update indicating that rulers are only rendered for the active page would at least indicate intended behavior. A user may not be pleased with the intended behavior but at least would know it is not a bug.
