Description Eike Hein 2014-11-28 14:41:05 UTC 
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)

Enable high DPI pixmaps

Even though there are some high DPI issues left to fix, enabling the
high DPI pixmaps does not cause any regressions and greatly improves the
experience.
