Fedora 25 Slow After Software Update

I'm new to Fedora, so be gentle :) I've been running Fedora 25 for a few weeks without a hitch. Then, one day, I shut down my machine and installed updates for Fedora. Well, after the update, my machine booted and it looked like the resolution on my monitor was improved (text was sharper / entire picture was smaller and fit into the monitor well). But it was dang slow. There was a very noticeable and annoying mouse / keyboard input lag to the point of just being unusable.

I booted and selected an older version of Fedora in GRUB. When I booted into that, the resolution was larger, but the thing ran great (no sluggishness what-so-ever).

This is a fresh build of a machine, so I know the specs are not the cause of this, and I assume it's some update to the kernel? How can I find what updates were applied and to see if they are to blame. Furthermore, is this a common thing to happen?

I have the same problem... the latest kernel maybe...

I would say that the two issues (picture quality and performance) are not necessarily related.

What is your graphics adapter?

Hi! Please send some more details, like kernel version, hw information etc. Are you on X.org or Wayland ? Did you monitored your system for the cause of these lags? I mean is it because of excessive IO activity or some CPU hogs? I'd suggest running nmon utility (not installed by default, but available in repos) for a while to find out who is guilty.

One more thing: what Desktop Environment are you using? If you don't know, or don't understand the question, you're probably using Gnome, as that's the default for Fedora. However, you might be using KDE, Xfce, Enlightenment or something else, and the answer may well depend on which one you're using.
