VST3 (?) midi plugin out of tune

Recently I tried the latest qtractor (0.9.35, tried both appimage from sourceforge and compiling from source) and noticed that the sound is out of tune. I'm using the sfizz VST3 plugin, and using the default instrument as examples, the A4 440Hz became higher A#4-ish 478.91Hz. I also noticed that the sfizz LV2 plugin is not affected and function normally. The previous version of qtractor works fine however.

I'm running qtractor with pipewire jack at 48kHz sampling rate. So far I've only tested sfizz since it is the only VST3 plugin I have. I'm guessing this is some sort of sampling rate problem (440/44100*48000=478.91, coincident?)? Asking here to see if anyone can reproduce this. Thanks!
