Font not Antialiasing

Perhaps.

Fortunately, semantics such as "most likely" are lead-ins to some guesswork. Certainly the problem resides with the font size and the window manager's willingness to render antialias for that given size and font family as it pertains only to the Qt application at runtime. As I said before, other applications are unaffected.

Whether it happens on other distributions versus whether it happens with other apps on mandriva is helpful for deduction and initial issue identification only.

I guess it might be worth mentioning that the previous version of Qt did not have this problem on this same OS.

Anyhow, the resolution is trivial enough.

I've been in contact with Trolltech support about the problem for quite a long time but they were unable to reproduce the problem. The problem is obviously in Qt, as Qt4.1 works fine with the exact same installation whereas Qt4.2 does not.

Do you have a vanilla Mandriva installation or did you upgrade it with some cooker packages or whatsoever?

No packages from cooker or contrib branches are installed, but quite a few from devel/2007.0/i586/media/main/release branch are installed as well as quite a few local installs that i compiled, as well as all applicable "updates" to existing packages (there were quite a few of these) but nothing "that should" have affected the Qt4.2.2 build or install.

I did leave all previous rpm-based Qt development packages installed prior to building Qt4.2.2 although Qt4.2.2 is the first that I have built from source for this Mandriva installation.

Another thing I am noticing, which may be of little consequence, but from Qt Designer 4.2.2 Open Source Edition, when I "Preview in" Cleanlooks Style, it seems to be loading a different palette from the palette that is used at runtime for any of the new 4.2.2 apps I have built.

I am making this guess because the window color from the "Preview in" Cleanlooks Style is different (slightly "pinker") than the window color that results from running a newly built app with Cleanlooks as the qtconfig default, or one built with QApplication::setStyle("cleanlooks");

As far as being a vanilla installation, my best answer is "no", unfortunately. I am happy to answer specific questions regarding the details of my installation, however.
