[Interest] terrible font rendering with QtQuick

[bane...@gmail.com]

Hi,

I  was working on a QtQuick application which will run on $MS windows. My 
app 
is *almost* done and  everything was fine until yesterday after i decided to 
deploy it
to other PC for testing.

The problem is the font render, it's really bad on 3 windows XP and 1 
windows 7, 
it looks exactly the same with this one: 
https://bugreports.qt-project.org/browse/QTBUG-31983

My Working Env:
Windows 7 64bit
Qt 5.2.1 mingw

Now, I have tried these method:
1. change font. [Not Working]
2. set `renderType: Text.NativeRendering`. [Not Working]
3. add system environment variable: `QML_DISABLE_DISTANCEFIELD`. [looks 
better, but still vary bad]
4. change Qt toolchains to Qt 5.0.1(the same version but working to the 
bugreporter), Qt 5.3.0 [Not Working]

The bug report was not updated since it was "Reported", and I can't emil to 
the reporter 
because i cannot get his email on that site, so anyone could tell me if there's 
something 
i can do to make it better?

of cause i tried that, that was the first thing i did after the problem 
exploded, but with no luck.
The openGL version of the testing XP machine is 2.1, which is enough for Qt 
(openGL 2+), 
Obviously Qt does not use that.

You could also try updating the OpenGL drivers to the latest version. The 
Intel drivers have improved vastly over the last 12 months.
