Also this has just happened to me....

Ok lasted until 2pm, now experiencing lag again after waking from laptop from sleep. 🙄

While my problem with this has always been irregular, I stumbled upon this on Reddit, and (touch wood) so far this morning it has worked.... Basically turn off 'Automatically adjust brightness'. https://www.reddit.com/r/MacOS/comments/16v1ltk/comment/k81vqzb/

I have a USB-C monitor and it is happening most of the time, but not always, almost as if there is a particular command or signal that triggers a crushing lag. (and I don't know what this is). Shifting the VW window back to the MacBook will resolve it, as will closing the MacBook and using the monitor only.

This just started happening to me yesterday too!!

@JuanP Just to note I think today's Mac os 14.1 release has solved this, right clicks are now back on 2nd monitor, but attention appreciated.

In a dual monitor situation (not mirroring), palettes on the second monitor are not responding to right clicks, i.e to update a references on the navigation palette. Move the palette back to the primary monitor and right click comes back. This was new behaviour with Mac Sonoma 14.0 installed today. Anyone else exhibit this?
