Public bug reported:
I installed 16.04 about 6 months back and got nvidia driver version
361.42 installed with it on my GeForce 940M card. glxgears produced
around 3800 fps on initial startup. Today I did a full upgrade of my
laptop and as a result nvidia 367.57 was installed. This produces around
800 fps and when switching between activities in kde and moving the
mouse I experience massive cursor lag etc. To see if it was related to
nvidia drivers or something having been upgraded in KDE I simply
installed latest PPA version (370.28) of nvidia and after a reboot this
totally fixed performance both in terms of feel and glxgears fps is back
to normal.
Obviously this is something of an upstream problem, however it seems to
me that perhaps the upgrade to 367 drivers should be delayed?
