I used G and H to zoom, restarted the program and the mixer still looks like this. Mixer 2 is fine
Resize and persisting issues
In some cases MixConsole does not restore its expected setup and proportions of elements within its different zones.
In some cases, areas of MixConsole are not redrawn correctly. As a workaround please scale the faders (using G/H) or close and re-open the MixConsole window.
