First of all, congratulations to the entire team of developers of this amazing tool. As for the possible "bug", I don't know if I'm doing something wrong and missing some detail, but anyway, I have the latest version of OBS installed on my machine and I noticed that when I have the option to hide the screen of OBS during recording, if I minimize the screens and go back to the desktop, when I return to the OBS screen, there is a rotation of activating and deactivating this feature. That is, if I go to the desktop and then go back into OBS, the OBS screen is no longer hidden, and if I go back to the desktop and then reopen the OBS window, its screen returns to stay hidden. The easiest way I've used to figure this out is by using the Windows shortcut key + D.
