Hi,

Today morning the update applet notified me about a security update, and along with that a lot of other packages were updated. I updated in the weekend before that. Since the newest update, plasmashell, kwin_x11 and X eats a lot of CPU (plasmashell is around 120%, X is 60%) and the whole UI freezes randomly for seconds. I have a ThinkPad X270 with an i5-7200U CPU.

The system is barely usable as it is right now.

Same problem on a Dell XPS 15 9560. Had to revert to 5.7.1 of QT.

How did you downgrade?

You use proprietary driver Intel?

I say about this software: http://imgur.com/a/Bt6ir, Here I use these drivers

Thanks for the help, this solved the issue for now.

Since the newest update, plasmashell, kwin_x11 and X eats a lot of CPU (plasmashell is around 120%, X is 60%) and the whole UI freezes randomly for seconds. I have a ThinkPad X270 with an i5-7200U CPU.

The system is barely usable as it is right now.

Are you using slideshow for wallpapers? Setting this to single image and restarting plasmashell fixed it for me!
set wallpaper to one image in configure desktop, then:
killall plasmashell; kstart5 plasmashell

Yes, I do. I have a random slideshow configured with a 1 minute interval that picks a random image from a directory with about ~250 images. I'll try disabling it and updating tonight.

OK I also had random image slideshow, but with 10 pictures. Doesn't matter have many you have. As long you don't have slideshow on any screen, and restart it will work as "normal".
