    Unusual Screen Behavior

    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.

    Here is the hardware information you asked for.

    Motherboard: MSI 970 GAMING DDR3 2133 ATX AMD
    Processor: AMD FD8350FRHKBOX FX-8350 FX-Series 8-Core Black Edition
    Memory: HyperX Kingston FURY 32GB (4x8GB) 1866MHz DDR3 CL10 DIMM - Black (HX318C10FBK2/16)
    Video Card: EVGA 1GB GeForce 8400 GS DirectX 10 64-Bit DDR3 PCI Express 2.0 x16 HDCP Ready Video Card Model 01G-P3-1302-LR

    Also, I installed Ubuntu 19.10 on my home theater PC and there were no streaks. My HTPC is hooked into my big screen TV through an HDMI cable, while my regular PC is hooked into the LCD monitor through a DVI-D cable.

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