We find extensions cause a lot of bugs so it's a good first step to
exclude the possibility that they are a factor.

Title:
[nvidia] gnome-shell uses 100% cpu, triggered by games while using
nvidia-driver
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
There's not much I can provide in terms of hard data, but maybe
someone can help with getting to the bottom of this. After installing
Ubuntu 18.10, I'm unable to use graphics-intensive games.
My setup:
ASUS F556U, with Intel® Core™ i7-7500U CPU @ 2.70GHz × 4, Intel® HD Graphics
620 (Kaby Lake GT2) + NVIDIA GeForce 940MX.
While the Nvidia card is being used (Performance mode set in nvidia-
settings) and I run a 3d game with Steam (happens e.g. with Black
Mesa, Euro Truck Simulator 2...), everything works as expected, but
after a relatively short amount of time gnome-shell starts eating up
more and more CPU for some reason, effectively taking over the actual
game. The game starts to stutter first, then slowly grinds to a
completely unresponsive state. If I manage to quit the game, gnome-
shell still does its thing. I'm sometimes even unable to enter the
overview mode in Gnome. The only solution is to reboot.
This does happen with nvidia-driver-390 from the standard repo, but
also with nvidia-driver-410 from the graphics PPA. This was not the
issue with Ubuntu 18.04. It also does not happen with nouveau, or with
the Intel drivers (power saving mode in nvidia-settings). There's also
nothing of note in the syslog.
