Every time my MacBook Air sleeps all of the windows rearrange across the laptop display and the connected Thunderbolt display. This is extremely annoying and did not happen in earlier versions of MacOS. Can anything be done to prevent this?
MacBook Pro 13″, macOS 12.2
Had the same issue on a new Mac Studio, brought this month, running Monterey.
Apple support will tell you to boot in safe mode, then reinstall macos before your support request can be escalculated, which is a waste of time.
THE FIX - Preferences > Energy Saver > Check 'Prevent your mac from automatically sleeping when the display is off'
It appears that when these m1 macs sleep, then wake - the connection to external monitors (I have 2 dell monitors and a Wacom Cintiq) doesn't register instantly, so our app windows are getting moved to the main display, then scattered across connected displays once they are recognised.
The above fix worked for me but this is clearly a macos bug that needs to be sorted by Apple

My solution may be specific to my setup, but I've found that waiting for both the macbook and the external monitor to wake up before logging back in seems to persist the pre-sleep arrangement. Hopefully this helps you and others. Good luck!
same here, very frustrating
I too have the same problem and its VERY frustrating.
Update: this solution seems to only work sometimes. I'm still unsure what causes it to only work sometimes, but I will try to update here if I do.
I think this is not the case, after some reboots or shutdowns I think you will have the same bug again... it's macOS definitely, no settings on a monitor could allow for a rearrange for the windows on an OS
Thank you Pani for your reply. I am not familiar with a monitor built-in menu or its Savings mode, and a web search for such for the Thunderbolt display didn't yield any meaningful results. Where is this menu found? (And I agree with Raffaele that a monitor setting should not cause a windows rearrangement.) Thank you.
I am also having this issue, new with MacOS 12. Currently using Monterey 12.3.1 on Mac Studio with 2 external (4k) displays connected via display port (Thunderbolt)
I have tried physically rewiring the displays to use different Thunderbolt ports - Mac always seems to work out which monitor is which and flip-flops them after sleep.
Did not have the problem on previous machine, 5,1 Mac Pro (not on MacOS 12)
update: I spent about 2 hrs with support from Apple. spoke to 4 different techs and reinstalled MacOS twice trying different things and no solution was found. The only option I have not yet tried is using a different set of monitors; my other monitors are not DisplayPort or Thunderbolt based.
It was the monitor settings which was set to Savings mode within the monitor built-in menu for me. No fault of Mac OS.
I think this is caused by equal edid/serials. macOS seems to not use all digits.
