Step 2

Problem description:
The sidebar displays incorrect width and height when units are in millimeters

Steps to reproduce:
1. Open LibreOffice Draw and set the options to display mm (Tools > Options > LibreOffice Draw > General > Unit of measurement: Millimeter)
2. Create a rectangle and change the width and height to 10.00 mm. Note that the Position and Size window* agrees with the sidebar for these dimensions. *right click on the rectangle > Position and Size
3. Deselect and reselect the rectangle. The sidebar now claims the width and height are 9.91 mm, however the Position and Size window correctly shows 10.00 mm.

Note that if a 10.00 mm grid is shown, the 10.00 mm rectangle aligns to the grid, whereas a 9.91 mm rectangle does not. This suggests the dimensions are actually 10.00 mm, even though the sidebar displays them as 9.91 mm.

Current behavior:
In the Sidebar, under Position and Size, the Width and Height display incorrect width and height.

Expected behavior:
In the Sidebar, under Position and Size, the Width and Height should display the correct width and height.

Additional comments:
-Tested on a Windows 7 (x64) machine using LibreOffice
-Able to be produced this issue in both LibreOffice Draw and Impress
-Though untested, I expect similar behavior when other units are used. This may be a rounding issue before unit conversions?

Comment 3 Nico Stuurman 2017-01-04 01:10:14 UTC
This bug is not present in Libreoffice (the first version with a sidebar), thus it's a regression

Adding "regression" to the keywords
Comment 4 Buovjaga 2017-01-04 08:29:32 UTC
Thanks for the test, Nico. Adding bibisectRequest.

Working on debian-stretch in the bibisect-43max repository, I see that
the bug entered LibreOffice in commit 36be3d94 ...

        Change-Id: Id81847bf7e989a3e49fbe8adaad23048956067df

Looking at a couple of numbers, it seems that the redisplayed
dimension is converted to nearest 0.01 inch and that result is
converted to the nearest 0.01 millimetre.

I am removing keyword bibisectRequest and adding bibisected and bisected.

The size is displayed incorrect and no matter which unit do you use. I have LO in Linux Mint and I confirmed this bug.

Problem on 5.3.4

As you can see on the screenshot the problem is also present when you select cm as unit, not only with mm. 

If you take the quotient between the value displayed on the menu and the one on the sidebar you get ~2.5. It seems the value displayed on the sidebar is on inches, even if it says cm.

Comment 15 Papamatti 2018-07-25 11:44:28 UTC
I can still confirm this bug in linux and lo This is very anoying, because it changes the sizes of objects in the document. And objects I didn't touch change their sizes and dimension lines too. For example 60cm becomes 62,59 and I didn't touch this drawing object. This happens while I changed another objects on this page.
Comment 16 Papamatti 2018-07-25 12:04:49 UTC
It'seems to work, if you DON'T TOUCH THE SIDEBAR.

OK, it doesn't work: for some reason, it started to work when using some drawing objects, then I selected a PNG picture and it failed, now even the drawing objects show different values in the sidebar and in the "Position and size" menu. (I tested on

I confirm that the bug is present in the version as well. Very annoying.
