I just upgraded my M1 Mac mini to Sequoia and am experiencing an issue where the wallpaper flickers black every few minutes. I’ve tried a variety of wallpapers and even reinstalling Sequoia, but it persists. The same issue is described in this thread on Reddit.

Anyone experiencing the same thing and know of fix?

I am experiencing the same thing on my M1 MacBook Air. Flickers black for split second when I have two windows open at the same time.
 
Not much opportunity to catch this since normally my screen is fully covered with windows, but I have observed this as well.
 
I have an M2 and also have this problem. Very annoying 🥲. Anyone tried using Safe Mode to see if the issue still persists? That's what Apple told me to do.
 
I guess they assigned all resources to getting Apple Intelligence work right. It feels like they are so behind everything they announced.
 
Has come good for me after running repair disk in macos recovery. Either that fixed it or i hadn’t actually reset smc previously and that happened during the process and fixed it.
 
Same thing on a 2020 intel imac. Glad to see it's some sort of bug. I have an lg 5k ultrafine connected and it happens on both monitors. The open windows and desktop files and menu bar don't disappear when it happens, just the wallpaper. At first I thought it was the wallpaper (one of the new sequoia ones) but it does it with a plain color one, too.

M1 Mac mini 16 ram 256 ssd. I run off external acacis tb3 enclosure with Samsung nvme ssd. Same. I thought it was obs. I started up on the onboard drive to up date and didn't notice, but wasn't on that long. It does seem to happen after away a few mins then come back, and click a few drop down menus at top. It happens randomly too. so not sure if it's graphics, ram. After reading this thread I will assume it's a bug. Hope to get a few more years out of this Mac mini.
 
My M1 max studio Mac flashes also. Just started doing it after the most recent upgrade to Sequoia 15.1 . It flashes the wall paper but not the desktop files.

I also have a 2020 mini mac with M1 chip running Sequoia that does NOT flicker.......

Do you mean 15.0.1? Or are you running the 15.1 beta and it's still an issue? I was hoping it would get fixed when that release gets out of beta.
 
So far on the latest 15.1 public beta (release candidate) I'm not seeing the problem. I have to sign off so we'll see how it goes tomorrow.
 
15.1 is not available as far as I can see.....how did you locate the download?

It officially comes out next monday but the Public Beta version 99% probably the same thing that will come out then, they're calling this the Release Candidate.

In System Settings/General/Software Update there is a Beta Updates option...click the i and select Sequoia Public Beta. Then 15.1 will show up for you. After install you may want to change it back to not getting betas.

Caveat is you are taking a small risk running beta software, especially if you need your computer for work. But so far so good for me. I only did it for this "final" beta release since it's the same as the software that will come out next week and I was getting annoyed by my desktop flickering hahahaha.
