This morning I updated my F22 system (only stable Fedora repos), which included multiple Kf5 packages. After rebooting, I find that window redraws are frequently messed up. This happens both on switching desktops and simply raising a window on an existing desktop. Occasionally the switching process leaves traces of the previous desktop on the new one, and windows are only partially redrawn. Both switching and raising are accompanied by rapid flashing between the old and new states for a fraction of a second before settling down.
I have an Nvidia graphics card, using the Nouveau driver.
AFAIK Kwin was not one of the updated packages. I used to be able to look at /var/log/yum.log or run "yum history" to check, but dnf has changed all that though no doubt it's still possible somehow (the dnf manual is a model of obscurity on this point).

I have a fully updated F22 system also with an nVidia card but I'm running the nVidia driver via rpmfusion. No problems like you describe. GeForce GTX 660 is my card.

Well if you update via dnf there is a dnf.log. If you do your updates via the apper systray icon I have no idea where the logs are....and I asked here and got no response.

Mine's a GT630, nothing special. Ironically, I had switched to Nouveau a
month or so ago because I had a problem with the Nvidia driver (system couldn't start X11 for some reason). I switched back and problem solved, so it looks like a Nouveau/Plasma issue.

dnf.log is quite different from the old yum.log. With the latter you had a simple time-sequence of install/update/remove actions. With the latter you have some internal logging data of no interest to the average user. There is a way to get approximately what I wanted ("dnf history info <number>", where <number> comes from a list of transactions produced by "dnf history", i.e. two commands to get more information than I really care about).
