Screen Tear Fix Kde

General Information

Fixing screen tearing in KDE.

Checklist

  • KDE Plasma (KDE 5)

Full Screen Repaints

Full screen repaints sometimes fix issues. (There is a warning that there is performance impacts, not sure how much)

  • Open “System Settings”
  • Under “Hardware”, click “Display and Monitor”
    • Click “Compositor”
    • Next to “Tearing prevention (vsync):”, click the drop down box and select “Full screen repaints”
    • Click Apply

Kwin Environmental Vars

The Kwin environmental variables solution does not impact performance like other solutions on the internet suggesting Full Composition Pipelining.


  • Create a new file and add some environmental variables.
    sudo vim /etc/profile.d/kwin.sh
     
    #!/bin/bash
    # Prevents screen tearing with NVIDIA Drivers (Only enable 1 at a time)
    export __GL_YIELD="USLEEP"
    #export KWIN_TRIPLE_BUFFER=1
    • Try first with USLEEP.
    • If that doesn't help, comment out that line and uncomment the Triple Buffer line.
  • Source the file to pick up the new variables
    source /etc/profile.d/kwin.sh
