I tried set up a fresh install of gentoo under virtual box. Everything went smoothly with exception of error after entering credentials on kde logging screen.

I have enabled 3d support in virtual box, but still I’m not sure whether we can expect working compositing under x in virtualized gentoo.
Don’t know whether exists better solution (let me know), but I’ve did was:
Creating file
/etc/X11/xorg.conf.d/disable-composite.conf
with below content:
Section “Extensions”
Option “Composite” “Disable”
EndSection
