You mean the font?  That's a system font -- it's measured in device pixels, and hence unaffected by the DPI setting.

Hmmm... yep... On X server with real dpi = 200 it works ok...

But is it possible somehow override it? I want to do full emulation of DPI change...

hmm.. ok if  we will suppose to fix Bug 4821, by using DPI scaling... then we should somehow use override Real system font DPI..., but now it probably invalid. or wontfix ;)
