QPainter::Antialiasing | QPainter::SmoothPixmapTransform bug on Linux?

[Nadia]

Hi,

At work I write app on Vista. I have set

view->setRenderHints(QPainter::Antialiasing | QPainter::SmoothPixmapTransform);

view->setRenderHints(QPainter::Antialiasing | QPainter::SmoothPixmapTransform);

To copy to clipboard, switch view to plain text mode 

Trying to open the same app at home on linux give me just plain window(without grahics element) and app hung up. I was looking for the problem and wnen I comment out

view->setRenderHints(QPainter::Antialiasing | QPainter::SmoothPixmapTransform);

view->setRenderHints(QPainter::Antialiasing | QPainter::SmoothPixmapTransform);

To copy to clipboard, switch view to plain text mode 

everything go ok.
