I've got a GeForce 650 Ti, and when I'm using the SW cursor (either manually
through xorg.conf, or enforced in a Reverse PRIME setup), the cursor begins to
flicker heavily in the Dota 2 game.

It seems that not only the cursor flickers heavily but also clicking is harder
(as if the click didn't work when the cursor is invisible).

I do not experience this with HW cursor or on the desktop or with the game in
windowed mode.

This is on GNOME 3 which disables compositing in full-screen applications.
