macOS 27 Golden Gate – Serious UI rendering issues on two different Apple Silicon Macs

Hello everyone,

Since upgrading to macOS 27 Golden Gate, I've been experiencing numerous graphical interface issues on both of my Macs:

MacBook Pro M4 Pro (work computer)

MacBook Air M4 (personal computer)

Both machines use completely separate Apple Accounts, yet they exhibit the same problems.

The issues mainly affect window controls, menus, buttons, and title bars. For example:

The red, yellow, and green window control buttons sometimes disappear completely.

Safari's toolbar or title bar occasionally fails to render properly.

When closing another application, such as Microsoft Word, parts of the Safari interface can disappear or become blank.

Certain interface elements are not properly redrawn when switching between applications or rearranging windows.

I've attached screenshots illustrating these problems.

I don't use Stage Manager or any third-party window management utilities. Both Macs are running standard macOS configurations.

These issues only started after upgrading to Golden Gate. Given that they occur on two different Apple Silicon Macs with separate Apple Accounts, I strongly suspect a macOS-level window rendering bug rather than a hardware or user-specific issue.

The problems are quite disruptive during everyday work.

Is anyone else experiencing similar issues? Has Apple acknowledged these rendering bugs, and is there any indication of when a fix might be released?

Thanks in advance for your feedback.
