Graphic issues on macOS Ventura

I’m running Nuendo 12.0.70 on a MacBook Pro M2 Max, macOS Ventura 13.5.2 and randomly run into graphic / GUI issues. Most of the time it affects the visualisation of the insert slots, send or direct output slots. Strangely enough, sometimes it happens only in the mixer window, sometimes in the inspector and sometimes in the channel settings (see picture).

Sometimes the slots turn white or brownish with a red brownish outline… it’s like Nuendo is on trippin techno party :alien:

Beside this, I also experience the so called “mouse icon bug” very often, mentioned here in this thread Mouse icon doesn't adapt

Anybody else experiencing these issues?
Any tips, tricks or workarounds to avoid these?

Thanks in advance,
all the best
