Was this issue ever resolved? I Just bought the new Mac Pro (2019) and I’m having the same issue except for me its horizontal scrolling that crashes the program and freezes the entire computer. This is the only thread I can find that has a similar issue. Cubase support has yet to respond to my ticket. I’m wondering if maybe Cubase 10.5 isn’t compatible with my graphics card since its on the newer side. My specs are:
Mac OS Catalina 10.15.5
Mac Pro (2019)
Processor 3.2 GHz 16-Core Intel Xeon W
Memory 32 GB 2933 MHz DDR4
AMD Radeon Pro W5700X 16 GB
Hopefully someone can get to the bottom of this before I run out of time and am forced to return the computer! haha
