[Interest] terrible font rendering with QtQuick
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?

In commercial projects, you can't just jump from one version to the next without extensive re-testing. In our case, there is even lots of paperwork involved (medical).

-Original Message- From: interest-bounces+kai.koehne=digia@qt-project.org [...] I tried openGL version, I also tried ANGLE which i think is the DirectX version, but later i just find out that Windows XP and ANGLE is not a supported combination. [1] Well give Mesa a try. It's easy, just drop in the opengl32.dll. You have to use that anyways to support remote desktop which invariably you find some of your users require. ANGLE supports Remote Desktop too, at least for non-XP machines :) I personally hadn't have a look at the MESA/llvmpipe things yet, but several people seem to be happy with it. Maybe one can come up with a list of pro's, and cons, and add it to http://qt-project.org/wiki/Qt-5-on-Windows-ANGLE-and-OpenGL ?

I'd probably still be plagued by people using VirtualBox or Citrix etc. It feels like hardly anyone runs desktop apps on their desktop these days. :) Ian ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

Re: [Interest] terrible font rendering with QtQuick
You could also try updating the OpenGL drivers to the latest version 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.

Actually the problem is that Qt uses it (because Qt doesn't know it's broken), resulting in glitches. That's why we have ANGLE and llvmpipe as workarounds. -- Join us Oct 6-8 at BCC Berlin for Qt Developer Days 2014!

Yes it's a QtQuick2 app, on my develop machine it works well, but when deploying to other computer, it performs bad on *some* windows7 and *almost all* windows xp, after the `distance field` disabled, all windows7 works as excepted, but windows xp still does not. I tried openGL version, I also tried ANGLE which i think is the DirectX version, but later i just find out that Windows XP and ANGLE is not a supported combination.
