Pocophone F1, broken audio with 64-bit processing enabled

Thanks the development team for this awesome piece of software! I am facing a bug with my newly purchased Xiaomi Pocophone F1. When I set the settings for Hi-Res Audio (as advised from thread
viewtopic.php?f=3&t=4014) and enable 64bit processing, the sound becomes muddy and overclipped, just as an FM station with too much static. When I deactivate it, it returns back to normal. I have currently a custom ROM installed, but I reckon that the issue persisted at the stock ROM as well.

Does this effect persists when you lower the preamp and/or activate AGC ?
What sampling rates are available ?
What happens when you switch between the available sampling rates ?

I have both AGP and preamp deactivated. Only songs at 44.1khz sound that way, with follow source frequency enabled. If I select frequency at 44100 and deactivate follow source frequency, all songs sound overclipped regardless khz. Even at 1% volume they still sound as described.

"Sound that way" - is that clipped or not ? So does any setting help ?
And what if you enable AGC ?

Another thing : if it's clipping it might be caused by the equalizer settings. What happens if you disable the equalizer ?

Equalizer is completely disabled. Playing music through phonespeaker sounds fine, no distortion.

Well, from that description I'm unable to distinguish the situations where it works and where not.
It seems to a problem of high-res-settings, some do, some don't. I suggest you use those that do.

To sum up: With hi-res settings and 64bit processing enabled, music sounds overclipped/distorted/muddy when playing 44.1khz via headphone jack. Forcing frequency other than 44.1khz, disabling hi-res settings, or disabling 64bit processing fixes the problem. If you think this is a bug, I hope you take a look at this.
