Screen flashing after upgrade

I finally got around to upgrading this (now old) machine from 16.04 -> 17.10 over the last couple days.  After fighting with DKMS it's finally booting and working... except the screen keeps flashing.

Why am I facing this reportedly fixed bug?

I managed to fix it by going into the NVidia X Server Settings and turning off this flag:

As soon as I unchecked that, everything was fine.

nVidia + video tearing in my IDE

I have been having some problems for the last few months where the menu items in my IDEs (plural) were tearing.  Sometimes they wouldn't popup, sometimes more than one would be highlighted, etc.

I found this article from 2 years ago which I couldn't really follow to the letter.  My nv only had one of the specified settings. I don't have ccsm installed, etc.

The ONLY change I made was:

1. sudo su - root
2. echo CLUTTER_PAINT=disable-clipped-redraws:disable-culling >> /etc/environment
3. reboot

So far it seems to be working fine.
