Description Of Issue
Scrambled screen when cursor moved from top or bottom of screen on MacBook Pro 15" 2016 after Catalina upgrade of OSX. As soon as cursor is moved from top or bottom of screen when Roon started screen scrambles. See screen shots …

The images don’t load properly.

Images load but when cursor moved they scramble. Move cursor back to top or bottom of screen then the images return OK. Obviously only an issue with Roon all other software no issue.

Hi Ian, @Adeeb’s message was that the screen shot images you posted on here do not display.
Looks like you broke them when you edited the post to add the headings … I have fixed the problem so they display now.

Hi @ian_mcloughlin,

Welcome to the forum! You mentioned that you are using the Mac Mini as the Core and the Macbook Pro as a remote only, correct? What operating system is your Mac Mini running, have you upgraded this to Catalina as well or is it still on a previous OSX version?

Since you are using the Macbook Pro only as a remote, can you please try reinstalling the Roon App on it and let me know if that changes anything with regard to this issue? You can use these instructions to reinstall the App:

  • Make a Backup of your current Roon Database
  • Exit out of Roon
  • Navigate to your Roon’s Database Location
  • Find the folder that says “Roon”
  • Rename the “Roon” folder to “Roon_old”
  • Restart/Reinstall the Roon App to generate a new Roon folder

Hi Catalina updated this morning and that seems to have fixed the issue.
