Bug Report Display for Monitor Capture not showing up on OBS

Hey guys, how's it going. I've been using OBS for the past 3 years now and I've got to first say thanks! It's a bloody great program, and I've been using it at work as well to help with our Quality Assurance ticket support system for software testing. It's been a great asset to debugging and helping to show developers where the key issues are at.

Now for this bug, I don't know if anyone else has experience it, but at work I'm having to use two different screens. One to use OBS, and the other record the capture I need to show the developers. Every other time, when I open OBS, the 'Display Capture' for one of my monitors isn't showing up on the main OBS screen. It's just black. I try changing it out by deleting the current source and adding a new one, or even changing the source from display 0 to display 1, but I always end up with a black screen. Once again, even adding a new source for the same display I need to capture, does not fix it. This tends to be happening to the right monitor display that I have. It works with the left just fine, but the right one seems to be having the issue in OBS.

When I close OBS, and then reopen it, does the bug fix itself. It happens every other time I open OBS.

Just wanted to pop in and report it. Hopefully someone can help me out with it. A couple of the other QA's have reported this to me and wanted to make sure I wasn't the only one. I searched the forums, and didn't see anything in regards to this same issue. I've uploaded the log file as well.

Make sure that all display captures capture 1 monitor per source. You can't have multiple sources capturing the same monitor.

I am. All sources are just on one monitor. I have multiple sources for different monitors. The problem is that one source alone, which captures the right monitor, goes blank on OBS when closing and reopening OBS every other time. When I get some free time, I'll post a video on here.

I see three monitor capture sources but only two monitors in the log. What's the third monitor capture source for?

The third monitor capture is for mobile devices in which I use a third-party application to sync with OBS to capture mobile device screens. It is rarely used.

Here is the video to show the bug that I am talking about: https://vimeo.com/208534024

The bug occurs every other time the OBS application is opened. Open, close, open, close...and so on.
