I am looking for a way to have KDE change the OpenGL version automatically on startup due to tearing . I did try adding that line to /etc/profile but it adds a delay to window dragging, and I do not get that when I manually change from OpenGL 3.1 to 2.0 and back to 3.1. Is there a way to change the OpenGL version via Konsole/Terminal? If so it would allow me to just run a script on startup. Or if anyone knows of something else which would work better, I am willing to listen and try.

systemsettings -> desktop effects -> advanced tab -> compositing type ->

Well I am not looking to change it manually every time I reboot, I want it to do the process for me automatically.

You don't want to do that at all.

If this is an nvidia GPU ensure to enable triple buffering (xorg.conf option. It's off by default) and then in ~/.kde/env create an executable (chmod +x) script

Code: Select all

#!/bin/sh
export KWIN_TRIPLE_BUFFER=1


Alternatively, you can shadow the kwin binary by eg. placing this script

https://github.com/luebking/KLItools/blob/master/kwin

into ~/bin or /usr/local/bin (any place ahead of /usr/bin in $PATH) and uncomment the resp. export there.

This is extremely late, but this worked!
