Just reporting this minor glitch as it seems to demonstrate a difference in the way Wavelab handles GUIs compared to other Steinberg products.
I have an instance of Izotope Tonal Balance Control 2 as an insert in the Master Section.
It’s a very simple graph of amplitude/frequency.
When Wavelab loads and the plugin GUI initialises the frequency scale (Hz) at the bottom of the plugin doesn’t appear. If you resize the plugin window then the window redraws and the frequency scale appears just fine.
This doesn’t happen in any other VST3 host that I’ve tried (including nuendo/cubase). Seems to imply that WL is doing something different when it initialises the GUI compared to other hosts ?
