as you can see in this video
there is a problem when we change the font dimension.
I have a LMDDockSite, and, over it, one centered LMDDockPanel and one left LMDDockPanel.
I set 100% dimension of font, text and other items on the "customize your display" windows section .
When I run the program, what I see on the two dockpanels is the same of what I see at design time (you can check the length of the labels).
After that I set 125% dimension of font.
When I run the program you can see that the ratio of the two panels is changed, the left panel is larger and the centered is smaller than before, and you can't see all the text of the label.
