Artist 9.5 problem with Big Sur

Hi all.
I have artist 9.5
I’m using an iMac 2017 model 5k with intel i7.
And with Big Sur
I have problem with graphic in Cubase. The graphics of cubase is corrupted

Any help please?

I’m having a graphics problem. I’m running Cubase 9.5 on an intel Macbook 2018 with Big Sur, with the Blackmagic external GPU.

If I move a block of audio the screen goes white. Several buttons look like they are corrupted, like a Commadore 64 loading screen.

+1 same problem

Any solution?
