Inside qpaintengine_raster.cpp, in the begin function, there is a check that decides which glyphCache is being used. It should pick RGBMask for the windows backingstore. I suspect that the bug is that it does not pick that path. Find out why, and you have your fix :)

cheers,
Gunnar

Hi,

The value is correct, it is 0 ( RGBMask ).

The issue is apparently that the Free Type font engine is used, which
still requires a bit of work on Windows. In the meantime, you can use
the native font engine by specifying the command line argument:

<app> -platform windows:fontengine=native

Thanks for reply! I test it, and can be sure it clear now.

D:\qt-everywhere-opensource-src-5.0.0\qtbase\bin>tabdialog.exe -platform window
:fontengine=native

I hope it's can be fixed ( or improved ) soon. Because I personaly thought many people don't want to see the un-clear font of the current UI.

Thanks again!

Hi,

Before this get fixed, we can simply set environment variable
"QT_QPA_PLATFORM" to the value "window:fontengine=native" under
windows, then all applications will work as expected.

IMO, it is not as bad as it seems, by doing this, users will become
more familiar with how to specify qpa plugin and its options at least.

Wow! Thanks!!
BTW, My fault, the vaule should be:

"QT_QPA_PLATFORM" to the value "windows:fontengine=native"

I test it on Windows 7 32bit, It works well.

I found another way, just use configure option: -no-freetype

The on Windows the issue gone.

QT_QPA_PLATFORM=windows:fontengine=native can't work now, -no-freetype is invalid too?

Any comments?
