Unusual Screen Behavior

[and003]

Today I installed the new Ubuntu 19.10 operating system. The install went well, but I seem to have some unusual behavior. Small streaks have been popping up on my display. They show up, disappear, and come back again. Even though I can still use the computer, these streaks are a distraction that I would prefer not to deal with.

I took a snapshot of these apparent streaks and attached it to this post to see if anyone can figure out what this is. This snapshot is from when I was using KDE Plasma, but these streaks have occurred in the Ubuntu desktop environment as well. Even though I intend to switch back to Ubuntu 18.04, I wanted to post this just in case someone had the same problem as I did. I have also reported this as a bug at the Ubuntu Launchpad forum.

If you are using nouveau display driver, replace it with nvidia driver.
