KDE4: Panel artifacts when using Thunderbird or OOo using NVIDIA drivers

NVIDIA has had the best drivers for Linux users for several years. Since early releases of KDE 4, however, some nasty artifacts appeared when running some Gnome based applications (like Open Office and Thunderbird) on systems with NVIDIA cards. These bugs have been reported to NVIDIA but haven't been addressed until now. According to this very long thread, the latest beta drivers from NVIDIA (180.x) the nasty artifacts should have disappeared. I compiled and installed this latest driver and indeed, the panel corruption when, for example, composing a new mail in Thunderbird does no longer appear. Finally, people running KDE 4 with NVIDIA cards are no longer nvidia-victims :)
