Screenshot showing the problem
When using SAL_USE_VCLPLUGIN=kde5, the font for text in dialogs, toolbars, status bars etc. is very narrow (and seems to be too narrow for its height). Fonts in the menu bar and in documents look right. (See attached screenshot).
This happens on X11 at 1920x1080.
Using SAL_USE_VCLPLUGIN=qt5, the font seems to have a normal width to height ratio, but fonts are way too large (see bug 122131).
With SAL_USE_VCLPLUGIN=gtk3, everything looks the way it should.
