Hello there,
Similar titled issues have been previously reported, however this one is fairly new and it's actually the latest nVidia update that triggered it.
In the latest driver update, nvidia decided to mess around with G-Sync and the way it is set up in their 3d settings.
G-Sync has been removed from the Vertical Sync setup and now there is a new 'Monitor technology' setting in the Nvidia Control Panel (under 3d settings) where you need to define G-Sync.
The problem starts if you have 2 monitors of which one supports G-Sync but the other one does not (it's a rather typical setup for any gamer who uses g-sync).
I myself have the same setup, I use the g-sync monitor for gaming and have OBS on the secondary which is a traditional 60 hertz LCD.
Ever since the new driver update, what happens is that OBS on the secondary monitor does not do a window-refresh whenever it's turned on (preview or streaming) unless a 3d application on the G-Sync monitor is in focus.
So if for example I were to try and switch scenes manually with the mouse OBS acts frozen (even though the application isn't locking up, it's just not refreshing its own window), the scene entries vanish, and it doesn't react at all unless another application on the same monitor triggers a refresh. (As an example if I start MSI afterburner, every time the graph refreshes I get a little bit of OBS time as well, otherwise it only comes back if I switch back to a 3d application on the primary g-sync monitor).
However if I pull OBS over to my primary monitor it is as responsive as before the update.
I would call this an nvidia issue (since they forgot to treat the two types of monitors in a separate way), however most other applications apparently have an antidote for this from construction (otherwise afterburner.. or a simple chrome window playing a video would freeze as well when on the secondary display and in focus)
Cheers!
