Upgraded my once-happy qt-4.5.0/kde-4.2.2 box (using oxygen), lots of weird rendering present, including biggies like kickoff/lancelet/krunner drawing empty boxes/frames. screenshot:
Seems the oxygen plasma theme is affected more than others I tried (including Aya, o3, which were mostly ok).
Oddly enough, the empty boxes persisted even after downgrading back to qt-4.5.0... need to further analyze my plasma*rc files before/after upgrade/downgrade.
Any ideas? Anyone else with good/bad experiences using qt-4.5.1 (esp against kde-4.2.2+)?
