* muffin version: 3.8.1-1~bionic0
* Distribution - Ubuntu 18.04, Mint 18.3
* Graphics hardware *and* driver used: Nvidia 390.48-0ubuntu3 (also replicated with with 396.24)
* 64 bit
Issue
Random black flashes will appear on the screen around applications from time to time.
Steps to reproduce
Install Cinnamon either on Ubuntu or install Mint. Log in, activate Nvidia driver, observe.
On the same Ubuntu system, problem does not occur when using a different desktop, even one that also uses GTK such as MATE. I also have three monitors hooked up to a GTX 1070, unplugging two and switching them around also does not resolve the issue.
I have installed Mint from scratch twice (second time to observe behavior) as well as Ubuntu to see if the issue occurred there. In all cases, the issue only occurs when running Cinnamon/Muffin.
Expected behaviour
No black flashes and for the screen to draw consistently.
