I confirm this. All applications using the QT toolkit seem to render fonts differently than the rest of the desktop (GNOME, GTK+ apps).
The fonts look to be bolder in QT apps compared to GTK+ apps. This seem to only happen when the new Ubuntu font is set as the application font in the Appearances settings, and only started to happen recently after an upgrade to the Ubuntu font package. I first observed this on Maverick, but since then I upgraded to Natty Beta 1 and the problem still persist. My theory is that QT apps use the "Medium" variant of the font instead of the "Regular" variant if the font in use has a "Medium" variant, because up until now the Ubuntu font did not have a "Medium" variant and everything worked fine. After the upgrade the newer version of the Ubuntu font has a "Medium" variant and suddenly the QT apps now render with a bolder font. If I happen to set the application font to the Ubuntu "Medium" variant in the Appearances dialog then the fonts in GTK+ and QT apps looks to be rendered the same. ** Summary changed: - qt font ubuntu larger + QT applications render with bolder font -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/751048 Title: QT applications render with bolder font -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
