Version: (using KDE 4.2.0) OS: Linux Installed from: Ubuntu Packages Resizing a program window goes smooth and fast. However, when a window edge touches the plasma panel, the resizing becomes very, very choppy.
I can't reproduce this using trunk r1184315 using a GeForce 8600 GTS with 256.35 driver. Is this still reproducible for you using KDE 4.5? If so, which video hardware and driver are you using?
this has either been related to blurring (did we have blurring in 4.2?) or possibly even about window snapping. However, bug is dated, 4.2 unmaintained since ages, the report has little relevant info and the reporter didn't reply to an information request for 17 months
