Toggling "Visible in Render" seems extremely slow in 2.93.105.0?

Hi,

I’m finding that Blender spends a loooooong time processing (>20s) each time I enable/disable an object for rendering with the little Camera icon in 2.93 LTS.
I’ve tried the same file in 2.83 LTS and do not have the issue, it’s pretty instant.
Enabling/disabling viewport visibility is fast in both versions.

Is anyone else having this issue? Could it be a 2.93 bug?
I can’t share the (multiple) files where I noticed the issue as they are confidential company IP, but can try to replicate it in a new file to upload if necessary.
