12.0.40 - Choppy/Laggy GUI when looking at full screen of audio events

Let’s say I have 8 tracks that each have a 15-minute audio event and I am zoomed so that I can see all 15 minutes of all 8 tracks (so basically my whole screen is taken up by audio events) - my Nuendo gets a bit choppy and just feels “slow”. As soon as I scroll away to where I’m just seeing a few shorter audio events, it becomes smooth again.

I have worked on these kinds of sessions since I started Nuendo, and this has only started happening on 12.0.40.

No crashing or anything, just laggy when my whole screen is taken up by waveforms.
