Nope. Never. And I already have it for about a year
Probably because I only install apps from extras-testing (with some exception on several apps from devel), not installing CSSU, not even using power kernel, only install apps I need and once I found an apps suited for me, I never bother to try other similar apps (unless it has better reviews and already considered stable, then I'll replace the old one with this) so no clutters, and never install any "patches"
