I've just tested with an IMX477 (HQ camera) as that was what I had on hand.
1280x720 YU12 yes is varying in frame rate by default.
Edit /usr/share/libcamera/ipa/rpi/vc4/imx477.json and reduce the max exposure time to 30000, and I get 30.01fps reliably, regardless of what I do with light levels.
That bit of the tuning file now reads

Code:
"normal": { "shutter": [ 100, 15000, 30000, 30000, 30000 ], "gain": [ 1.0, 1.0, 2.0, 4.0, 6.0 ] },
