Recently upgraded from 10 pro to 11 pro. Displaying Kontakt instance it displays very small, less than half the size seen in C10. In order to make it useable (large enough) I select new option “Make window resizeable” There is suddenly a loud buzzing noise. Closing the Kontakt instance does not fix it. The project has to be killed and restarted.
We had the same issue reported some days ago…
The often misleading topic titles make it hard to find them…
Perform a forum search, maybe you have more luck
btw, the Kontakt version would help…
