Before taking any drastic measures..... 1.  Create a new user and see if it also has the issue.  It could specific to your user. 2.  Think about posting to the KDE list as more experienced folks may hang out there.

Time to reinstall F34, and this is when I discovered that it is nearly impossible to reinstall F34 on a btrfs system without reformatting /home too (!?) I thought that was to point of having /home on a different partition (which looks like it during install but it isn't in btrfs, I didn't know that). Having TWO full backups i started from scratch and reinstalled, and this time "standard partition" and "xfs" I don't think I'll touch btrfs again until the Fedora installer can deal with this absurdity. And now, back in business, writing this in my new KDE!

It is possible, it's just a bit non-obvious how to do it. This test case explains how to to it step by step. You already have a Btrfs installation, so Setup steps 1 and 2 are done. You can go to the how to test steps. The critical steps are 9 and 10. In particular 10 is not obvious that it's creating a new subvolume for '/' and that's why the Btrfs file system isn't reformatted, and hence the existing home subvolume is retained, and just assigned to /home in the new installation. https://fedoraproject.org/wiki/QA:Testcase_partitioning_custom_btrfs_pres... And yeah we need a better way to document this than a test case.
