I don't think the qt update forces a KDE rebuild, but I'm not 100% certain on that. > > Are there a way to roll back emerge-sync?

I doubt that.

I've never really had issues with KDE, but I don't really use many of the KDE applications, such as kmail/koffice/etc. I also have baloo disabled (I think - that thing is like a zombie that never quite dies). However, it really is an integrated set of packages. When it wants to update all 150 of them, best to just let it. You can always save binary packages to make it easier to go back, or use snapshots/etc at the filesystem level. However, there is really no getting around the forward march of progress on Gentoo. I'm running it on a Phenom II and sure the updates can be slow (just waiting for full Ryzen support on a longterm kernel to make the jump). A release-based distro has a different set of tradeoffs but it would generally result in you always staying on a stable version of KDE, for the small selection of distros that support KDE well. -- Rich
