@PG1,
I’ve identified a reproducible issue that affects ARA editors when they are embedded inside Cubase.
WaveLab Pro itself works perfectly, and SpectraLayers standalone also works perfectly.
Even WaveLab used as External Editor (separate floating window) works without any issue.
The problem appears only when WaveLab or SpectraLayers are loaded as ARA editors inside Cubase, and only when Cubase’s internal scaling is changed (for example +25% or --25%).
Windows scaling stays unchanged.
Keep Windows scaling fixed (e.g., 125% or 100%)
Open Cubase
Change Cubase scaling (+25% or --25%)
Load WaveLab ARA or SpectraLayers ARA
The embedded ARA window shows visual artifacts (incomplete redraw, frozen areas)
Restore Cubase scaling → issue disappears
Since WaveLab works correctly in standalone mode and as External Editor, the issue seems related to ARA embedding inside Cubase, not to WaveLab itself.
Thanks PG1.
Just to clarify: Cubase is not changing its scaling dynamically while the ARA editor is open.
I set Cubase’s internal UI scaling to --25% before launching the program.
Cubase starts with that scaling, I open a project, everything works normally, and only when I open the ARA editor (WaveLab or SpectraLayers) the redraw issue appears.
So the problem happens even without any dynamic scaling change.
It’s enough for Cubase to run at a scaling different from 100% for the embedded ARA window to show the artifacts. Or you just saying there’s no ways where Wavelab ARA can follow any scaling change even by default?
