Audio waveforms are out of sync when zoomed out

When importing video clips the generated waveform will display incorrectly, out of sync with the audio playback until zooming in by a significant degree (allowing only aprox. 6sec of the timeline to fit onscreen). The audio playback itself is entirely fine and plays as it should, the problem is only in the waveform display.

 

The problem happens most consistently when working with clips from NVIDIA's ShadowPlay screen recorder. I figured it might be caused by a problem with the way the software encodes the audio or as a result of it recording in variable framerate. However, even when completely re-encoding both the video and audio and forcing a constant framerate, the issue still persists.

 

I've searched google and this forum in particular extensively and have found similar problems, such as the waveform completely disappearing when zoomed out, but nothing like this. Regardless I tried all solutions given to fix the alternative issue I mentioned, but nothing seemed to work.

 

Below is the waveform displayed correctly, in sync with the audio playback.

Below is the same waveform with the timeline zoomed out by one tick, now being displayed incorrectly and out of sync with the audio playback.

This is on the most recent version of Premiere Pro 2020 (14.7.0 Build 23) but is a problem I have encountered for years now. Any help or insight would be greatly appreciated.
