seems like MFR is sort of broken...

Last night I set up a render queue with about a hundred comps that are basically the same (a 1m30s text animation, the actual text is only thing difference between the comps). First 50 took about 4 to 5 minutes per comp to render, then it suddenly went up, now taking over 50 minutes for the same kind of comp. There is a green part in the renderbar and the render is still progressing (sometimes showing a lightgreen part in the bar), but checking the info it says 'Concurrent frames rendering: 0 '. This seems incorrect. 

So my guess is that MFR is where it broke down somehow. But maybe it's something else, I don't know.
Anyway, it's now much slower then rendering without MFR (it will render a comp in just under 10 minutes without MFR), defeating the purpose of MFR.

At least for now using MFR on a render queue seems unreliable.

I'm running AE 24.1.0 on a M2 Ultra Mac Studio, 128GB RAM, macOS 13.6.3.
