Hi Radek,

Taking a closer look, it may actually not be pixmap drawing performances. It looks like interruption when moving, that may just come from touch screen event coming irregularly, or anything else delaying the refresh of the map.

I am looking forward for the new kernel, it would probably solve the issue!

Regards,
Thierry

This application is just great. Probably everybody is interested :)

There are 2 things different in QtMoko. 2.6.29 kernel and Qt 4.5. I think Qt 
4.5 improved the performance. The kernel can be the problem. I am now testing 
2.6.31 kernel and performance of your app is good. Also scrolling in web 
browser improved with 2.6.31 so it can be something in 2.6.29 kernel.

Thanks for this nice application.

Radek
