One of the ways I use OBS is that I have a webcam in my window so I can see who's at the door, so I leave OBS running all the time. After I recently updated OBS I've been witnessing strange events if it's been running more than a day or two. When I go to launch simple play money poker programs, ones I've been using for years, I'll get "out of graphics memory" errors. Once they start, they keep happening every time I attempt to load them. If I close OBS the problems go away. I tried leaving OBS off a few days and the problems never resurfaced. Then I ran it again for a few days and they started up again. I've got a pretty beefy system with a GTX 1080 with 8 gigs of video ram. I used the option under help to upload my logs. Hope this is helpful.
