Description of Issue

Since I upgraded to build 475, I am experiencing problems with how Roon displays its output on the built-in Retina display and the external monitor.

If I start and open Roon on the external monitor and then move the Roon window to the built-in Retina display, the top ~half of the window get blanked out (two images to illustrate):

ROON WINDOW MOVED TO BUILT-IN RETINA DISPLAY

Likewise, If I start and open Roon on the built-in Retina display and then move the Roon window to the external monitor, in this case most of the Roon window gets blanked out (two images to illustrate):

ROON WINDOW MOVED TO EXTERNAL MONITOR

It doesnā€™t matter what I am looking at in Roon, e.g. my album list etc, it still happens. I was just using the Qobuz screen as an example.

I am also experiencing this on my 2017 MacBook Pro which is also running Catalina 10.15.1 and the same Roon versions as on my iMac. The macBook is connecting to the core on my iMac. In this case the external monitor is a Dell U2713HM [2560 x 1440].

So at the moment I have to leave Roon on the display I started it on to avoid this blanking out problem.

Is this a known issue and/or is there a fix / work-around? :slightly_smiling_face:

Hi @Jon_2019,

Iā€™ve moved your topic over to the support category so that @support will follow this up for you.

I had exactly the same issue when switching Roon between a 2012 Macbook Pro (retina display) and (an ancient) 27" Cinema Display. In my case, as Iā€™m still running Mojave, I reinstalled v416, so suspect this is specific to v475 rather than anything to do with Catalina.

@Jon_2019, a quick work around is to resize the Roon window after moving it to the other display. This worked for me before I reverted to v416.

@DaveN, Brilliant, that does it - thanks for the work-around tip! :grinning:
