What’s the word Steinberg?
Everything working fine in 10 - suddenly Waves plugins are going black after having been opened once?
Mac High Sierra.
Seems to be the same on Mojave?
also was a problem on Windows 10 with the Waves version 10. I heard it was an open GL problem there so it should be related to graphics card drivers. I couldn’t help my friend with his problem before installing Windows 7 - then it worked. I am not a Waves user myself, but I have run into 2 friends with the exact same problem on Windows. so I doubt it is a Cubase problem as it’s been a problem with other DAW’s too
