A minor bug was found which causes the knobs and hover popup labels to flicker to an offset position and back. This is showcased in the screenshot by the "Osc 2 Frequency: 3.8 semitones" label.
Typo correction: only the hover popup labels flicker and not the knobs themselves which otherwise continue to work as expected.
I have seen that flickering too. It is _very_ visible in this free synth: https://mastrcode-music.de/en/vst-plugins/t-force-zenith/
