I have my composition running and i move some nodes. then you see me hit F3 to reveal apps. I click on the Composition Viewer and it comes to the front for quick period then hides itself behind the editor. If i then dont click on any nodes in the Editor and hit F3 again and click on it the loader comes on top.
If i do move some nodes and then try and reveal it again its start jumping behind.
Hopefully it will be clear from this video.
We retested on macOS 10.13 and are no longer seeing the bug, either on the Vuo version where it was originally seen (Vuo 0.5.1) or more recent Vuo versions. So this appears to be a macOS bug that has been fixed.
