I cannot configure Kwin's compositing to use OpenGL 2 or 3.1 and raster graphics, Kwin output shows something like "opengl driver recommends xrender based compositing"

Why is this happening? It's quite annoying. I know the setting can somehow be forced (not sure how exactly, wasn't very clear) but I don't want to have to force kde to use OpenGL, it should just accept it.

I am using an nvidia card on the proprietary drivers. I have the opengl useflag as well and mesa as well as opengl installed. I also have 20-nvidia.conf set in xorg.conf.d.

Code:

Section "Device"
    Identifier "Nvidia GTX 550-Ti"
    Driver "nvidia"
EndSection


Solved:

Oops, I had not configured opengl to use nvidias implementation.

Solution was to run:

Code:
#eselect opengl set 1


Or in other words run "eselect opengl list" find the nvidia entry and set it to that.
