They are both using 4.5 recently downloaded from the main trolltech download for 4.5, one says qtsdk-2009.1. That's the one that works that I downloaded a few weeks ago. The other says qtsdk-2009.2 that I downloaded when someone pointed out that there had been a revision.

Absolutely no change in my code base at all, just building it with different patch revisions of the sdk.

Scaling if I take the one built with 2009.1 and drag it into all different shapes is no trouble at all. The one built with 2009.2 is 'corrupted' looking no matter what geometry I drag it into. This happens cross platforms and cross video hardware as well.

Both of those screen shots were built cleanly a few minutes apart from each other, just switching between the sdks to build them with of course a clean all and setting the default Qt in qtcreator to use the right default Qt for the build.

I'm not alone with this either, several other people on the project have built it on several platforms, varying linuxes, Windows and differing hardware and had the same results.

If anyone has any pointers to where to look for known syntax changes between the 2009.1 and 2009.2 revisions it would help as I really don't know a lot about the code. I figured it would just be a patch increment with such a minor revision change.
