Usually I double click the top window bar to maximize or revert back to the position a window was in, need this efficiency and now when double clicking top window bar the window maximizes on display then quickly bounces back to same position. I realize I can press option key above green circle, beyond annoying on all screens and more so on bigger external monitors. once in a while if I double click fast enough with some luck it does what its supposed to (maximize or revert back to original pos wich is usually half or quarter screen). tried a few settings. was guessing something to do with double click speed, don't know. this is beyond annoying and having to waste time on it is also annoying
