           Summary: DPI is inconsistent between the plasma desktop and
                    other apps
           Product: kde
           Version: 4.6
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: belegdol at gmail.com


Version:           4.6 (using KDE 4.6.2) 
OS:                Linux

A picture says more than a thousand words:

I have a 1920x1080 15.6' screen. As I was told, gnome overrides the dpi (to 96
it seems), while KDE uses the real one:

$ xdpyinfo | grep -B1 dot
  dimensions:    1920x1080 pixels (351x191 millimeters)
  resolution:    139x144 dots per inch

The problem is that plasma desktop seems started before the dpi gets detected,
resulting in fonts smaller than everything else. Overriding the dpi to 96 seems
to bring the consistency back (systemsettings in this screenshot was started
after the override):

Reproducible: Always

Steps to Reproduce:
1. Log in to KDE desktop on a high dpi screen
2. Start an application

Actual Results:  
Font sizes are inconsistent

Expected Results:  
Font sizes remain the same
