With support now for Retina displays, the scale needs to be changed to accommodate the increased resolution. The export to Print Composer works correctly, but the working window shows the scale at half (or double, not sure what wording would be correct). For example, if the desired scale is 1:50,000, the print composer will show 1:50,000, but the working window will need to be set to 1:100,000 for the scale to be correct for 1:50,000.

Please try with 3.4.4

I should have qualified that I'm using 3.4.4. I'm attaching two images. One is a screenshot of my work environment. Notice the relation of the label of the lake names to the shapes. As you can see at the bottom of the screenshot, that scale is set to 1:290,000. I exported the map in Print Composer at 1:145,000 and the scales are identical. When I do this in 2.18.x, I set both the working environment and Print Composer the same and get the same result.
