Version: 4.0.2 (using KDE 4.0.2) Installed from: Debian testing/unstable Packages Resize of KDE3 application windows is very slow, and not continuous. I have configured KDE4 to not update the contents of windows while resizing. kwin 4.0.2
I can confirm this with kwin from kde 4.1. Actually it's non-kde4 window resizing that is slow.
And me too. With both kde3 and kde4. But only with GTK Apps (e.g dia, gimp, inkscape). How to reproduce: After resizing the window of a gtk-based app to the smallest allowed size, further resizing is not smooth, but rather happens stepwise.
