Hi Martin, this issue isn’t just about the silence line being bolder in 12 compared to 11.
The issue is about the new Cubase 12 feature, “Smooth waveform drawing”, which is enabled along with the Interpolate Audio Waveforms setting in Preferences.
On Mac it seems this functionality cannot be disabled even though the box is not checked.
There was a previous topic where I explained everything in detail but never got any confirmation from you although I asked for it.
There are actually two bugs and one feature request.
It’s all explained here, just read the different posts carefully :
