Hello,

I am new to the forum - but no newbie to Qt (I use it since version 2.x)...

I have a very strange behavour in an application I am currently developing. I use Qt4.7 on MacOS Snow Leopard.

I built an App which simply adds several sprites to one bigger image (drawing the images using QPainter) and stores the image. It additionally stores a list of coordinates.

When I use QCoreApplication everything works fine.

If I use QApplication the data file with the coordinates is exactly the same. But the image file is not!
The output image size is the same but the complete contents (images + position of them) is scaled down by about 10%.

I firtst thought about uninitialised variables but the compiler did not complain about that. The behaviour is completely reproducable. I use unit tests to test the files I create - every file shows the same problem!

Has anybody an idea?

Thanks
