Canon R5 sensor shifting during liveview

Having a weird issue with a Canon R5, even with IBIS turned off and lens stabilization turned off the sensor seems to bounce around or even rotate when turning liveview on or right after an exposure (Meaning the liveview does not match the photo that is about to be taken). If you focus, the sensor ‘resets’, moves and now matches the photo that is about to be taken. Re-focusing for each shot sadly is not an option.

Canon says this is not a camera issue since Canon EOS Utility doesn’t do this, is there a way to turn IBIS off from smart shooter 4 that I’m missing?
