What brand of camera are you using? My Oly/Lumix cams behave, but Fuji acts like a bitch, and and the IBIS will shift-glitch. I sold my X-T5 partly because of this. -
How impactful / costly would it be to get a camera without IBIS? If it's just a matter of buying another body to add to your existing ecosystem then maybe it's worth it? -

Thanks, yeah I can fix it in post with optical flow in davinci resolve, but I often just deliver my footage to production houses, so I sometimes even feel emberassed as I can see it. And I am afraid it may hurt my business. When walking forward I almost never see the issue. Only when doing a kind of slider shot. Moving left to right without even taking a step. -
Equipment with stabilisation like cameras with IBIS or lenses with OIS can have very different reactions to motion. For example the normal IBIS mode on GH5 vs the IBIS 'tripod mode' where it tries to eliminate all motion. I've been aware of this for a long time as one of the OIS lenses on my Canon 700D refused to let me pan the camera, and would hold the composition steady and when it ran out of travel it would jerk suddenly. It felt like the frame was 'stuck' and I had to 'pull hard' on it to get it to unstick and then it would jerk into a new position (that it would then wrestle with me to try and hold that new position). The jitters you're seeing from IBIS mechanisms may very well be some kind of undesired response to the motion of the camera perhaps? I have IBIS and non-IBIS cameras and I previously frankensteined a rig with four of them and then walked around the backyard with it. I can probably dig up the details / footage if that would be of interest, although the cameras are quite different (IIRC the non-IBIS camera was the OG BMPCC). I've sometimes wondered what an IBIS mechanism does when it's switched off. Does the sensor get held in place by the motors, or does it get disconnected and flap around? If I turn my GX85 upside down to get the battery / card out of the bottom I can feel something moving around inside it, and I just always assumed it was the sensor. I just grabbed it and did a quick test: - camera off = rattling inside when I turn it upside down - camera on / IBIS on = no rattling - camera on / IBIS off = no rattling I guess it's held in place somehow? In terms of seeing subtle jitters in the footage, does a touch of stabilisation in post fix it? If so, that might be the quickest / cheapest option. If you're doing hand-held work then you might really miss the IBIS. When I was using the OG BM cams for street shooting (BMPCC / BMMCC) the OIS lens did a great job of pan and tilt but OIS doesn't stabilise roll at all, so the image had very unnatural motion and I had to stabilise the roll in post.

I'm not sure about how to answer parts of your question, but I would suggest that if you want IBIS, but to be able to fully lock down the sensor when IBIS is off, some of the Nikon cameras do that.
