There’s a bug in Safari 15.0 where it sometimes re-positions open windows when waking from sleep by moving all the windows down an amount such that the bottom of the lowest one is at the bottom of the monitor (or something like that? They all move down a lot).
If happen to place your Safari windows up enough so that another app’s window can be visible on-screen under them (chat in my case), and you have a few too many windows open in Safari (ahem!), then you might be very annoyed to have to over a hundred windows all back up again.
Now, you could go through your heap of open Safari windows, but if you’re a programmer than you might (likely incorrectly ;)) think it’d be faster to write an AppleScript to move them all back up again. Not that I’d do such a thing, you understand, but, purely for educational purposes, here’s the kind of script one might write (or the second version if the first one took 6 minutes process the > 100 Safari windows you had open) :). This one moves all Safari windows up the same amount to keep their relative positioning and moves them up as much as possible while still keeping the window positioned highest on the screen below the menu bar.
Disclaimer: I write zero to two AppleScripts a year and never really learned AppleScript. There’s almost certainly better ways to do this. But it works for me and fixes my windows after Safari munges them again. So GoodEnough™ 🙂

Here it is in a gist for easier copy/edit, etc.
