Official Patch Notes
OBS Studio 32.1.2 is a targeted hotfix for the 32.1 line. The main fixes address scene-list selection lag introduced in 32.1.0/32.1.1, nested menu appearance, and theme warnings tied to missing properties. For creators and streamers, the most relevant item is the scene-list lag fix because it affects day-to-day scene management during production and live-show setup. This release also inherits the larger 32.1 audio mixer overhaul, WebRTC simulcast support, source-copying changes, and multiple stability fixes from the 32.1 branch.
