I was able to pin down the issue to the second monitor now.
I can open any plug-in within the effects rack just fine. As soon as I move the effects rack to the second monitor and I try some critical plug-ins (e.g. NI Raum or Super 8), Cubase shows a white Plug-In Box without content and the music keeps playing but everything else is freezed.
Sombody else experiences the same issue and found already a solution?
Not quite sure when it started, but I think around 2 days ago. I installed the update to 12.0.10 five days ago.
In between I made a Mobo-Bios-Update. Nothing else. Also I made sure that I took over the same bios settings.
I’m using a ASUS HD7770 1GB DDR5 with 3 Monitors connected. Two equal (1920x1080) and one old Samsung (1600x1200). Issue as shown in the picture on the second monitor of the two equal monitors.
Is the other screen (where it doesn’t happen) the Main screen? Do you have the latest driver installed? How are the 3 screens connected (are there 3 HDMIs)? Does it happen, if you connect only 2 screens?
as I wrote above, when I’m doing it on just the main screen, everything is working fine. As soon as I try to open the plug-ins on the second screen. It will freeze. I updated once again the graphics drivers but nothing changed. I will try what you recommended below and get back to you.
