See https://bugzilla.mozilla.org/show_bug.cgi?id=378927 for upstream bugs about this. You can confirm this by visiting http://mrmazda.no-ip.com/auth/dpi-screen-window.html to see reported DPI and default FF px setting will probably be about half what xdpyinfo and 'xrdb -query | grep dpi' report. > > The crossover point is 144 DPI. As long as your X DPI is below this, FF will behave as you are used to. If your system is really a 163 DPI system, and you don't like the scaling effects, you'll have to reconfigure something so that FF thinks or knows the DPI is less than 144. In about:config you could set layout.css.dpi to 143 as a direct workaround. Also you could set the system's Xft.dpi to less than 144. > > If your system is not really a 163 DPI system, you need to reconfigure X so FF doesn't think that's what it is. > -- Thanks for the information, it really helped. xrdb reports: Xft.dpi: 120 Setting that value in about:config gives a decent display. If I go higher (say the 143) then portions of the window on the right and bottom aren't visible. I'm assuming that the value from xdpyinfo is probably incorrect, though I don't know at this point where to look. darrell -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
