[solved] Poor rendering on Windows machine

[haiying]

Hi I'm using Qt5.2.0
I wrote and run good on Ubuntu machine. But when I recompile and run it on Windows7 machine , which has Qt5.2.0 mingw, the result is very poor, not as good as it on Ubuntu. And the following messages output.

---

Hi and welcome to devnet,

There are two solutions proposed:

change your Qt package by installing the ANGLE version.

ensure that you have the latest OpenGL driver installed

Hope it helps

Hi, many thanks for your advice.
Could you please share the info where I can get the installer of ANGLE version for windows machine? I will try it.
Thanks and kind regards.

You can find them on the download page, it's those without OpenGL in their name
