Qt with DirectFB won't display properly.

[Francach]

Hi,

I'm developping an embedded app for PowerPc with Qt 4.6.0 on a SUSE 11.2 host.
Cross-compilation works fine, but when I run my Hallo World app on the powerPC development board characters are barely legible and the lines around labels and boxes are not solid.
The display on the development board is 640*480 with depth of 16.
I've tested the DirectFB driver with the test tol fbtest and it functions fine.
It must be something to do with the configuration with Qt, but I haven't been able to find it yet.

Thanks for any tips.

This is my configuration for Qt:

./configure -confirm-license -release -no-fast -no-largefile -no-accessibility -no-sql-ibase -no-sql-mysql -no-sql-odbc

I'd just like to chime in that I'm also seeing this issue (or something very similar) in 4.6.3. I'm using an OpenSUSE 11.3 host and cross compiling for ARM. I have my physical screen dimensions set correctly in QWS_DISPLAY, but my text characters are either offset very high in their respective containers, or not visible at all, and I'm having various other display glitches.

I can post a picture of my screen if it helps, but does anyone have any idea what could be causing these general display issues?

My configure line is:
./configure -opensource -confirm-license -no-qt3support -no-javascript-jit -no-script -no-scripttools -no-webkit -qt-gfx-linuxfb -release -nomake examples -nomake demos -static -embedded arm -xplatform qws/linux-arm-g++ -little-endian -prefix /usr/local/Trolltech/Qt-arm-4.6.3


Thanks,
Chris

Edit: I realized that I'm not using directfb, so we may not be having the same issue. However, the problem description sounds extremely similar, and i can't find any other posts which describe a similar graphical error.
