Or so they say at least when I asked them about a changelog.
Are you using the 2.01.54 or .56 build?
2.01.54 had some fixes related to OSB/Xsplit sync (make sure you are using the latest Xsplit 2.x and OBS), .56 fixed a problem where the live preview shows a shifted video.
Please let us know if this helps or if more support is needed.
