System Information
Operating system: macOS-12.2-x86_64-i386-64bit 64 Bits
Graphics card: AMD Radeon R9 M370X OpenGL Engine ATI Technologies Inc. 4.1 ATI-4.7.103

Blender Version
Broken: After bisecting it looks like 5b299e5999 caused this.

Short description of error
The viewport's "World" cavity type doesn't work. 2 things that I think I should mention are that changing the cavity's sampling settings still slows down the viewport, and that the "Screen" cavity type still works.

Also the behaviour of this error is different between Windows and macOS M1 .
Was used d29a079cb6 to compare both systems.
While rotating the cube on Windows the world cavity is visible. As soon as the middle mouse button is released the world cavity disappears completely.
On Mac the world cavity disappears completely while rotating the cube. When the middle mouse button is released the world cavity flashes to its full brightness and then the brightness is diminished to half or less but still visible.

Exact steps for others to reproduce the error

Enable cavity
Set cavity type to "World"

I can't replicate the problem. Must be MacOS related.

I should also mention, the Screen cavity type still works!

I can replicate the bug in my Windows machine.

Can confirm on Windows and Mac. Jan 26 was the first daily build where the world cavity stopped working, while the daily build of Jan 25 still worked.
After bisecting it looks like 5b299e5999 caused this.

Also the behaviour of this error is different between Windows and macOS M1 .
Because some things have changed since then I am using d29a079cb6 to compare both systems.
While rotating the cube on Windows the world cavity is visible. As soon as the middle mouse button is released the world cavity disappears completely.
On Mac the world cavity disappears completely while rotating the cube. When the middle mouse button is released the world cavity flashes to its full brightness and then the brightness is diminished to half or less but still visible.
I also attached the blend file. broken_world_cavity.blend

In fact it was a slip in the test. I can confirm.

I'm seeing a slightly different behaviour, but I think the cause might be related. For me World cavity still works but "Valley" effect (or AO) disappears once samples go over 18. Whereas "Ridge" effect gets progressively weaker with more samples and is basically invisible at 500 samples.

Also the Cavity is much noisier overall than before.
Maybe the result is different because of different GPU, I'm using rtx 3060ti on Windows for example.

I was about to report this issue. Just want to mention and confirm that this isn't working on Linux also. It seems, visually, that the "Valley" is not working, I see that "Ridge" seems to be ok...
