Hi,

I have just found the same error.

Starting to show my students the difference between calculating an area with 
planimetric /ellipsoide difference.

We use EPSG 25832  (UTM32 N EUREF 89)

In the Project properties the Measure tool are set to CRS  ON  and Ellipsoide 
None /Planimetric ??? Strange when I have choosen a CRS with an Ellipsoide

Then I change the Ellipsoide to WGS84 - Click on CRS - and sometimes it is set 
back to None or Clark 1866.



When I try to calculate an area - without any changes in the None /Planimetric 
- and secondly change the ellipsoide to WGS84 and recalculate - the area gets 
smaller!!!!!!!



There is a Bug report #11713 on the same issue from November - still open set 
to normal....This must be a blocker

it is messy as already said by Alexander, and that ticket should be reopened.



sometimes seems to follow a pattern like:



If you open the project properties from the menus the ellipsoid changes, but 
not the canvas units.



If you open the project properties from the bottom right icon/shortcut the 
ellipsoid does not change, but units do.



other times it seems it just messes up everything regardless of what you have 
choosen and how you open the project properties.



This to me is a major issue because the user never knows how reliable are the 
measurements being done (with the field calculator) and if numbers can be 
compared with the ones computed previously.

cannot confirm here, it shows degrees

for better results

the "size type" of the background must be set to "fixed" (and then give it the 
proper size).
