macOS Sequoia Massive memory leak

So this seems to be an issue with all the recent macOS versions, the windowserver process just seems to eat more and more ram. Now when im running a single safari window with 5 tabs, mail, messages, notes, and onenote, the windowserver process i guess needs 5gb of ram to do its job. I rebooted, it started at 250mb, as soon as i start opening things it skyrockets. It seems to eat about 1gb per app window open. Closing the apps does not lower the processes ram usage. It will continue to grow with every app i open. I did a fresh reinstall of the OS, reinstalled all 3rd party apps by hand, of which i only use a few, and the issue persists. These numbers hold true on my m3 MBA with 16gb ram and my partners m1 base MBA. This is ridiculous Apple

Same issue here. And I believe this is related to iPhone Mirroring App.

I tried to keep away from that for 2 days, then the memory usage is acceptable even I connected to two 4k external displays (3 displays if internal included).

But when I accidentally clicked on the iPhone notification on my Mac this morning, the memory usage of window server went up instantly and keeps growing. Also that usage never decrease since then.

I am using macOS 18.0.1 on M1max MacBook Pro, so I deeply believe the memory leak problem is still not fixed.

Seem to have the same issue but with Safari specifically. Four tabs open, 35.39 GB of application memory used 😳

My MacBook Air is now virtually unusable, since "upgrading" to Sequoia 15.1.1. Out of memory about every 5-10 minutes. Rebooting 3-4x per hour. Closing apps doesn't seem to help.

I just submitted a detailed support ticket to Apple. Hopefully something will be found
