Hi tonrin!

Thanks for sharing your fix, I know a lot of users will appreciate it.

For anyone using this fix, make sure you run an update-grub after making changes.

To see if this will work for you as a fix before modifying that file and running update-grub, you can run the following (I can't credit the original creator as this has been posted on about 40 different sites in relation to this fix)

sudo tee /sys/module/rcutree/parameters/rcu_idle_gp_delay <<<1

and then try optirun glxspheres64

If that fixes it, you should update the grub file.
