How can I make a fade-out truly linear, like the lower waveform in the image? When a seemingly linear fade is drawn as volume automation, it results in an exponential fade-out instead, like the upper waveform in the image.
Which Cubase version? There were versions before Steinberg introduced “sample accurate” volume automation that did some weird stuff with automation at higher buffer settings.
One might think this (the picture below) would result in a somewhat linear fade-out, but no—it ends up being the same exponential fade (I believe that’s what it’s called) as in the first waveform in the first image above,

Have you tried to check the waveform display in other tools? Sometimes the waveform is merely a more or less accurate approximation depending on the choice of weapon.
For an event fade-out -6dB lies vertically half way between the top (0dB) and the bottom (-inf dB).
That means 50% power reduction happens at 50% of the vertical size.
Have a look where -6dB is on a volume channel automation lane.
The ramp starts at 0dB and ends at -inf dB. The spot in the middle is at -12dB. To the right of the ramp I placed a -6dB event.
So a 50% power reduction happens after around 35% of the vertical size.
Either you create a lot of breakpoints, but unlike what you tried before you should rather go for “every 50% of the time between two points I insert another breakpoint at 6dB lower than the previous one” AKA a lot of work
or you search for a plugin that has a different scale on its volume fader and automate that instead of the channel volume.
