If this is NOT related to compositing you perhaps suffer from the issue documented in bugs 178269, 183263, 241094, 243094 - this should (hopefully) be fixed in 4.6
If this IS related to compositing (ie. shift+alt+f12 makes everything fast again) * Disable the blur effect * (esp. when using the nvidia driver) disable decoration animations in oxygen and use a not animated aurorae or not aurorae at all (sorry martin ;-) * blacklist the lanczos filter (see bug #243181) * in case you've an nvidia GPU, see bug #234463 Thomas >> Visit http://mail.kde.org/mailman/listinfo/kde-devel#unsub to unsubscribe <<
