Version: (using Devel) Installed from: Compiled sources Compiler: GCC 4.2 OS: Linux Plasmoid movement is not always smooth. Mind the "always". Actually it works perfectly well about 50% of the time. The other fifty percent however are rather painful : the plasmoids won't move until the mouse is released or no mouse movement happened during several seconds which induce a strong feeling of irresponsiveness. This bug really annoys me and I'd gladly help fixing it if anyone can point me in the right direction (no KDE 4 programming background yet but more than two years working on Qt 4 apps should do).
Turns out tweaking my (NVidia...) card settings a bit got rid of that annoying bug. Forcing it to use GlyphCache and InitialPixmapPlacement as advised on techbase did the trick.
