Bug report #11920
Scale inconsistently changes when adjusting map extent

Within Print Composer, SCALE changes when changing XMIN or YMIN for a map, which makes it difficult to accurately draw a map. Changing SCALE alters XMIN, XMAX, YMIN and YMAX. Behaviour is inconsistent, as changing YMIN or YMAX does not effect SCALE.
To reproduce the problem, change XMAX either by changing the Item Properties of the map, or by dragging the boundary of the map.
The parameters XMIN, XMAX, YMIN, YMAX, SCALE and the size parameters WDITH and HEIGHT are all entrancingly linked. What is required is the ability to fix some of the parameters, such as XMIN, YMIN and SCALE and let the other parameters adjust accordingly. Ideally the user should be allowed to choose which parameters to fix and which to allow to float.

I have the same problem.
2 maps in the same size no problem - Change one of the maps and scale change too.
Map 0 is in 1:5000 Map 1 1:5000 (same size) Map 2 1:5100 (Smaller XMIN, XMAX, YMIN and YMAX) I have to change scale from 1:5000 to 1:5100 to fit.
