Waveform zoomed in causes zooming lag

Can you guys confirm this bug.Make the waveform bigger meaning adjust the slider on the top right of the screen and adjust it to you see the waveform grow. Than zoom in on your project using horizontal and vertical zoom it lags. If I adjust the waveform slider to its default position meaning the lowest it can go (small waveforms) there’s no lag zooming up and down left and right.


I cannot see this on my system (Cubase 8.5, Mac OS X 10.11.1). The Zoom is the same (fluent) independently on the Waveform Zoom level.

Hmmmm maybe it’s my graphics card in my 09 iMac.

I have MB Pro Early 11 here.
