Once in the top bar, once in the back button:

I'm not sure why this happens with Rectangle but not with the native system.
If Rectangle cannot diferentiate it, maybe reducing the double-click possible time (or making it customizable?) could mitigate it (for me at least).

Thank you :)

Thanks for reporting! I think this can be fixed and will see what I can do.

[antonio1475]

Thank you! To add just in case: it also happens (and more importantly) in the search bar (eg. double click to select a word to edit it)

Cheers

I hit a snag on this one, where the item being clicked on is very often misreported by the Accessibility API and Slack. Effectively there isn't a way for Rectangle to distinguish if you've clicked on any of the items in the toolbar vs the toolbar itself with confidence. MacOS works fine because it has access to the actual window items being clicked, whereas Rectangle must rely upon the Accessibility API to get a proxy object of what's clicked, since the window is not in Rectangle's process.

With that in mind, I've thought of some alternatives and none of them have quite panned out. Making the double click time customizable is an option, but I'll give this some thought. There might be a better solution.

Ah, thanks.
Is this an Apple limitation or a Slack limitation (i.e. could Slack improve this?)?

Since I had hid the menu bar icon, I just saw https://github.com/rxhanson/Rectangle?tab=readme-ov-file#ignore-an-app

If that (or a similar option) also ignored the "Double-click window title bar to maximise/restore", I guess it would kinda mitigate this 🤔
