I enabled the user feedback back option for KMail and then wanted to know, what it actually sends, so I clicked on "Show the raw data that is going to be shared" (which BTW I missed in the global plasma system settings "user feedback" page).

Looking at the data for my screens setup data, I found strange values:

 "screens": [
        {
            "dpi": 109,
            "height": 1440,
            "width": 2560
        },
        {
            "dpi": 58,
            "height": 683,
            "width": 853
        }
    ],

My actual setup are 2 displays, one with a 3840×2160 and 1280×1024 screen resolution.

Perhaps there is a bug in kmail or in qt/kde which leads to these wrong values for my setup, as I alread filed a bug report for kmail, because it's windows are distorted, sub menues appear at the wrong place etc. pp. Other applications do not have this problem).

See https://bugs.kde.org/show_bug.cgi?id=414924

I would like to see, if plasma settings sends the same values, but I found no "raw data" button there. Is there any way to get the raw data there?
