I have a problem with my qt designer.
When i start it, the cpu usage grow until 85-90% and i can't do my work how i could.
Have someone any problem dealing with mine and how do you resolve it?

I think its a bug of qt designer, because yesterday, i run it for the nth time and it has a nice behaviour with the cpu.....(in a few words i could work without any lagging)....

I work on a linux station (kubuntu O.S.) and i used the mesa driver for my ati radeon that has the "direct rendering" up.
