           Summary: Support hi-dpi scaling meta-bug
                    (QT_DEVICE_PIXEL_RATIO)
           Product: konversation
           Version: frameworks
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: konversation-devel at kde.org
          Reporter: hein at kde.org

Konversation should properly support the new hi-dpi scaling in Qt. As of now,
various things are broken - check the DEPENDs of this bug.

To try it out:

a) Enable this line in main.cpp: 
   app.setAttribute(Qt::AA_UseHighDpiPixmaps, true);
   (Line 106 at the time of writing.)

b) Grep the source for other "FIXME HIDPI" instances that might be relevant.

c) Export QT_DEVICE_PIXEL_RATIO=2

d) Make sure your font DPI is set to something high like 192 (you can override
it in System Settings)
