Bad altitude hold with 3.4-rc5

Hi, I have strange altutide hold behavior with 3.4-rc5. (genuine pixracer, ZMR250, 4S, 2204 motors, 5045 props, ~20% hover throttle).

With sticks at 50%, the copter moves up/down by 2-3 meters.

(i have other issues, like compass not calibrated after restart; ekf anomalies; but those are already reported on other topics.)

Here are my logs and the full param list:

Can you please help? I cant use any of the modes like this, except stabilize and acro. Would be nice to have a reliable RTL/Land and AltHold.
