Hi all,

In short: adding "-graphicssystem raster" to my Qt4 applications' command line improved performance drastically for me. There's also a method to set it programmatically, and an environment variable [2].

Hi Sanne,

Thank you for the tip! I may look into setting the variable by default on X11 TDE sessions to aid in improving Qt4 application performance.

I have been doing this for some time on kmymoney 4.x (my only regular KDE4 app) and it helps a lot in minimising effects of multiple redraws.
