Hello.
I have Radeon HD4650 AGP video card.
I installed package catalyst-test from AUR.
I have orginal xorg.conf generated by 'aticonfig --initial'.
I have kdemod3(without compiz-fusion).
The problem is:
- slow and laggy scrolling pages with text and images in Qt4 applications.
Qt3 and GTK apps runs smoothly(almost - little slow redrawing windows in opposite to xf86-ati-video driver).
I tried run Qt4 application with parameter '-graphicssystem opengl' and effect is better but still slow scrolling. Moreover drawing menus is slower.
I tried also Qt4 application with parameter '-graphicssystem raster' and runs perfectly.
So adding parameter '-graphicssystem raster' to *every* Qt4 application is the solution, but not *practical* solution.
Is other solution for this problem?
If not, how can I add parameter '-graphicsystem raster' to every Qt4 application one time.(I want write '-graphicsystem raster' once not e.g. 50 times).
Can anyone help?

I you're using qt >= 4.7 you can set global variable to change graphics system.
Create ~/.kde4/env/qt-graphicssystem.sh:
export QT_GRAPHICSSYSTEM=raster
Or you can use gui - kcm-qt-graphicssystem.
