tags 537801 + unreproducible thanks Hi, I tried kcachegrind 4.2.4 with Qt 4.5.2 and I can't reproduce the bug using intel or nvidia driver. which desktop environnment do you use ? do you use compositing (compiz, kwin effects, etc...) ? do you use some extra package to enhance qt/gtk integration (gtk2-engine- qtcurve, etc ...) ? cheers, Fathi
