Weird glitches during restore from minimalization of any app

[kecinzer]

After update to macOS 13 I mentioned weird graphics bug during restoring windows from minimization.
Firstly I thought that is application bug, but it happens to any app (for example Apple Notes, Telegram, DayOne, WhatsApp).
When I click to minimized app in dock its windows will instantly appears for part of second and then disappears until restore animation is finished. I captured it in video.

Anyone else have this bug? Restart didn't help. macOS 13.0.1 22A400.

I tried it on macOS 13.1 beta 3, still happening. I already sent feedback.

This issue still persist on 13.1 (22C65).
Apple not responding to my Feedback.

Can you reproduce it every time? I think I saw it happen once for me, but now I can't seem to reproduce.

 

[kecinzer]

Yes, I can reproduce it any time.

 

[kecinzer]

Still persist on 13.2 (22D49).

I can't reproduce it on Venture 13.1. Weird that you see it every time. It also happens if you create a new local macOS account for testing and log into that?

Edit:

OK, I can reproduce it, but not every time. It seems related to having the Dock at the bottom of the screen and having the ”Minimize windows into application” turned on in System Settings.

What happens if you temporarily move the Dock to one of the sides – does it still happen for you then?

I'm not seeing this issue on a Mac Studio with either the "Minimize" or "Genie" setting. Perhaps your Mac is under-spec'd for running Ventura?

 

[FreakinEurekan]

Not seeing it here either. M1 mini with 16GB RAM.

I already tried it with dock on the left - same issue for me.

My mac is under-spec what? I have MacBook Pro 14" 2021 with M1Pro. A tried it also with only external 4K display connected and it still happens.

 

[fisherking]

have not seen this on either of my macs (M2 air, intel imac). try creating a test admin account; does it happen there?

 

[star-affinity]

OK, it seems unrelated to where the Dock is positioned.

I can reproduce it, but not every time. To reproduce, have ”Minimize windows into application” turned on in System Settings. Then with an app window in front, press ⌘M to minimize it into its app icon in the Dock. Then click the app icon in the dock to un-minimize the window. Now do this several times in succession; ⌘M, click app icon in Dock – ⌘M, click app icon in Dock – ⌘M, click app icon in Dock…

Keep looking at the window and you should eventually see what @kecinzer means. Here's a screen recording I captured:

Now, why it happens every time for you @kecinzer and not for the rest of us I have no idea about. 🤷‍♂️

Clearly you Mac should run it just fine. What resolution is your monitor set to?

 

[fisherking]

did you try a test account? and what happens if you change from scale effect to genie effect? (just curious).

Did you try to reproduce it? Try with the Notes.app.

Happens also with the genie effect.

I'm also wondering if it happens with every window for you @kecinzer?

For me it happens every now and then with the Notes.app window, but for reason not at all or not at often with other windows. Hmm...

Thank you for this test. It not happend every minimize and restore. Its same as you.
It seems that some apps dont have this issue.
Apps that are affected: Notes, Music, Day One, Beeper, Messages

 

[kecinzer]

Can someone test please, if its fixed in 13.3 beta2?

 

[Larsvonhier]

I tried it on macOS 13.1 beta 3, still happening. I already sent feedback.

Seems to depend on the GPU used. No such glitches here with 13.3b2 on a RX280 in Mac Pro.
edit: after enabling/disabling stage manager and minimizing/restoring to dock there is a one-time faulty flicker of the app window contours but after that everything is back to ok as long as stage manager is left at same state.

 

[kecinzer]

Thank you for the test.
So you said I can try enable stage manager if fixes it. Ok.

This is happening on macOS 14 as well. And I believe this did happen on versions prior to 13 as well. Previously I had this pretty much with the Music app only, now happens with most of the apps.

To reproduce the issue, you need to go to Settings -> Desktop & Dock and enable Minimize windows into application icon. I use the Genie Effect but also happens with the Scale Effect. The glitch happens in 60-70%, so sometimes windows open smoothly.

It is also possible to reproduce the bug with Minimize windows into application icon disabled. In this case, you need to minimize the window as usual but restore it by clicking the application icon in the dock, not the thumbnail. The same 60-70% of attempts have this glitch.

I had this bug on an old MacBook Pro (mid-2014) with a discrete Nvidia GPU and now have it on M1 MacBook Pro (2011).

I am 99% positive Apple does know about the issue unless they are blind. This is how they care.

Just wanted to add that Messages, Calendar, Mail, and Finder apps work well. I can't reproduce this issue. Also, some third-party apps such as RubyMine (I am a software developer), and a few other apps are fine. At the same time the Music app, which is also a native macOS app, and Slack which is not, both have this issue.

This might be something in the applications, the way they implemented 🤷‍♂️

 

[kecinzer]

Enabling Stage Manager fixes this issue 😄.

 

[r2.d2]

Indeed but there is another problem with it – I don't like it 😀 And it still doesn't replace the dock completely.

 

[kecinzer]

I had same feeling at the beginning, but now I can't live without Stage Manager. I'm used to it.
