I just noticed that the scale legend in the bottom left part of the othogonal viewports disapperas when the landscape mode is active. However, it does not return if in placement mode again.
After editor restart, the legend is back until mode is switched to landscape again.
-Create a project with 4.14p1
-Watch the legend bar being there
-Switch to landscape editing mode
-See that the legend bar is gone
-Switch back to placement mode
-Observe that the legend bar is still gone and cant be brought back.
