Possible Bug: Manipulate a Window Interacts Differently (And Unreliably) With Different Applications

Howdy folks. I am posting an interesting phenomenon I am experiencing ever since the latest Big Sur update. Tagging @peternlewis since we had discussed this in another topic. I have included a video recording of what I am talking about to explain it further.

Basically, manipulate a window no longer works reliably. Sometimes it will reposition the window correctly, and sometimes it simply won't. There doesn't appear to be a rhyme or reason as to when it works or not. Stranger still, now some applications even animate moving the window around, while other apps do not. They never did this before. Finder and TextEdit seem especially prone to this issue.

Peter suggested it could be interference from other apps that also control window positioning. I have Better Touch Tool and Rectangle installed, so I temporarily disabled them, but the issue is still present.

I first noticed it after the latest Big Sur update (now running 11.5.2), however I cannot guarantee that it was that precise moment when the issue started to arise. I'm stumped as to why it's happening, and even went so far as to uninstall and reinstall Keyboard Maestro, but that has not had a visible affect on the issue.

So if anybody has any ideas as to what might be causing the issue, I'm all ears!

Screen recording (hosted in my Dropbox account)

Sorry I wasn't able to embed the screen recording in the post...when I converted it to GIF format it was still too large so I had to put it in Dropbox.

EDIT: Maybe my GIF isn't even working...but I gotta eat lunch so I'll try to fix it after :laughing:

EDIT 2: I can't seem to get the screen recording and/or GIF image to work properly so they may not show up using that Dropbox link. Maybe somebody has a suggestion in that regard...

Unrelated: GIFs have to be <1.5 MB

Unfortunately, when it is something specific to your Mac, it is very hard to suggest what the issue might be.

Things to try include:

  • Safe Boot.
  • Create a fresh new account, and see if it happens there.
  • Disable all Launch Agents & Daemons and Login Items and see if it still happens.
  • Give up and install a fresh OS and start again from scratch.

I'm posting this just to share an update with anybody who comes across this post nowadays.

I never have found a solution to this issue but I found a workaround. Basically I use a global variable along with a repeat action to ensure the window is properly positioned. Since global variables are unique to each machine, I have it set to 1 on my iMac and 5 on my MacBook since it is the one that has the problems.

Update: I posted a macro here that uses an AppleScript to ensure proper positioning in case folks continue to run into this issue in the future.
