[MeeGo-dev] MeeGo Tablet 1.2 system not responses at Qt applicaiton exit

[Dong Li]

Hi list,

I've got a problem while programming with Qt on Intel Oaktrail platform.

In order to improve the application performance, I took use of the Qt
"raster" backend [void QApplication::setGraphicsSystem ( const QString
& system )], and the proformance was really improved a lot in
comparison with native backend.

However, the problem is that the entire system will not response at
applicaiton exit, and afterwards, system would recover in 10 or 20
seconds.

I monitored the CPU usage during that time, and found Xorg and
application itself were at 90% above.

This problem only happens on Oaktrail HW platform and on every Meego
Tablet 1.2 system. This is the one I've been using:
http://repo.meego.com/MeeGo/builds/1.2.0.90/1.2.0.90.6.20110628.2/images/meego-tablet-ia32-oaktrail/

Does anyone have idea about this?

Thanks a lot!
