I am having the exact same problem on one of my two laptops.
First, please note I am not using Ubuntu or Kubuntu. I am running Arch Linux. I know this isn't an Arch Linux bug reporter, but wanted to note that this might be an upstream issue due to my having the problem on a different distribution.
Another thing worth noting is that my laptop with Intel graphics doesn't seem to be bothered by this bug (though I only use that laptop around once a week or less). My Nvidia laptop has this issue.
So I'm thinking:
Either this is a KDE bug, or an Nvidia bug.
Are you guys running Nvidia?
Although we use different distributions, our interests are the same, so I hope we can pinpoint the issue.
