After updating to the latest version (7.10.0.6) for Windows 10, my previous settings and any newly created layouts that share desktops have massive flickering video.
I have 3 desktop monitors and I have setups to stream each desktop with and without a camera overlay input. All of these are now useless and any new sessions created which use direct desktops as inputs are useless.
When selecting one scene to share monitor 2, I will sometimes see flashes displaying output from monitor 3 and vice versa.
