Monterey seems to not remember which display should show which windows after sleep wakeup

Well, I "solved" the bug for my circumstances. I have 3 Viewsonic monitors, all exactly the same model (VX2478-SMHD) , I kept one in storage and used 2 with my Macbook Pro. I switched one of them out with the one I usually keep in storage and that did the trick.

When I moved I must have grabbed the one I usually didn't use, and apparently MacOS couldn't tell the difference between the two and kept flopping them around. For some reason two of them (the "right" pair/combo are different enough and gives MacOS what it needs so it can distinguish the two every time.

Reporting back: I tried both, ie. screen sleep after 15 minutes and unchecking "Close windows when quitting an app". Neither worked. In the morning all windows were on monitor 1. But thanks for trying.

It seems the latest Monterey 12.5 patch has fixed the issue?

I just did a quick sleep and wake up, windows seems still in same place. I will continue do more testing, including a long sleep at tonight when I go to bed.

Thanks for everyone 's feed back

Problem still occurs:

I have MacBook Pro 16 with 64 GB Ram, 8 TB SSD Name plus 2 LG UHG 4k monitors and Monterey 12.5. Will the apple moderator of this chat jump in and provide answers. This is very frustrating to have to arrange the windows and I have 30-50 windows opened. Taking a break should be OK and Apple please advice

Thanks

I've updated Sandman and created a brief web page, linking to the latest version. It is here. Right now the latest version is 0.1.2. 

The issue with the first version was it only worked for some displays. So it now shows a button in a single window when your computer wakes, which you click to complete the restore. This isn't as elegant, but more universal.

I have the new MacBook Air M2, Monterey latest 12.5.1

Same problem, connected to my home monitor 24" Samsung as a second screen (thunderbolt-hub-hdmi), and also when connected to my office monitor 32" Eizo (thunderbolt directly).

I tried all possible variations with mission control, like adjust spaces to last usage or monitors use different spaces

Some few times the windows appeared correctly, but most often they land all on the Macbook display after wakeup.

Can you forward it to devs instead of giving this generic reply? It clearly is a bug.

Same behavior, just submitted Product Feedback - Apple for this.

We can try and hope for something to happen.

Me too on my new MBP 16 as well

I have the same problem, Mac 16" M1 Monterey with 2 extra screens on usb C : all my windows are messed up when I wake up my mac or even when I unlock it... :(

I am also having same issue ever since updating to Monterey on my M1 Mini. Wasn't an issue with Big Sur.

I had the same problem, updating Rectangle seemed to fix it

What do you mean updating rectagle. Could you elaborate, please
