    Hi,

    recently I am testing Kubuntu since Mint has dropped the KDE version in Mint 19.

    Kubuntu still suffers from old issues even though many had reported them.

    One of it is tearing when moving windows themselves or playing contents (YouTube) / scrolling contents....

    (Another one is theme issues when apps are running as root another one dolphin lacks of root processes):rolleyes:

    Working fix for tearing (Nvidia) proprietary drivers installed:

    Locate /etc/profile.d/kwin.sh. If not present create kwin.sh there.
    Edit / create with kate.

    Code:
    export __GL_YIELD="USLEEP"
    Save it there.


    This is the only needed and only working fix (no triple-buffering needed here) I have tried countless of different settings at compositor to avoid tearing and many other fixes like tinkering with other configs.

    Kubuntu impresses me. Anyway there are some old issues which should not exist anymore. Also the dolphin cannot run as root politics seems to be idiotic...

    Since Mint has dropped KDE I am a bit lost what to use in the future. I do not want to return to cinnamon anymore.


    BTW: Does somebody know how do I apply the KDE themes to root apps?
    They look ugly when running as root......but look fine when running as user_name

    Hi,

    i don't know if it's still works but you can try this to run KDE themes to root apps :

    Code:
    sudo apt install gtk-chtheme
    then Alt+F2 and launch the apps
    I've moved from Mint to Manjaro Xfce.
