Bug ? cubase graphics laggy when operating channel eq

When using the channel eq if I click on the line and move the band around the frequency graphic , the play head cursor and the channel meter readings become sluggish., there is no stutter in the audio and everything behaves as it should if I use the eq control knobs below.

It’s not a cpu issue, this will happen even if I load an empty project with one audio clip.

Also maxed the buffers but still same problem.

Mac ventura
Cubase 12.0.52
MacBook Pro 14 M1 Pro
this happens in rosseta and native,

I’ve tested some more and I get the same issue when using cubase 11. I now think this is a problem with my system.

I never noticed this before I updated to Ventura. Is any one else running cubase on silicon mac having any gui issues?
