Im having a similar issue with Cubase 14 on my MacBook Air M4 and on the Mac mini m4 with 26.1 (25B78) Tahoe

Specifically, when scrolling through the project timeline, the video and audio clips drag noticeably, causing a lag that disrupts workflow. This is happening with just audio tracks and a video track with no plugins. Its a fresh cubase install on both Macs
