OK I sussed it out. It’s not when I single click the buttons it’s when I double click anywhere in the window.
Deselecting ‘Double click a windows title bar’ in Dock Preferences stops it from happenning.
…but it happens when I click anywhere in the window :/
I see what Joe means, using the Fullscreen Status node, when manually gone OUT of fullscreen mode, double-clicking anywhere on the window maximise the window, like it should do only when double-clicking the window bar. Disconnecting the node fixes it.
None of us on Team Vuo have been able to reproduce this using multiple macOS versions, including 10.14. Possibly if one of you could make a screen recording similar to BSS’s, but encompassing all the steps from Run, that could help.
Thanks for the new video. We were able to figure out that this is an apparent macOS 10.14 bug where, when ‘System Preferences > Dock > Double-click on a window’s title bar to [minimize/zoom]’ is enabled and ‘System Preferences > Mission Control > Displays have separate Spaces’ is disabled, un-fullscreening a window then double-clicking on it causes it to minimize/zoom.
