Resolve Viewers with Resolve Icon and Dots

Hello,
I've never seen anything like this. And I haven't been able to find a solution. The solution is probably simple. I'd appreciate your help.
I just installed Resolve Studio 18 and, with one exception, everything looks good.
The exception? Every viewer shows the following on the screen.
- The Resolve Icon
- "Davinci Resolve"
- "Studio"
- A pattern of dots
I've attached an image.
Thanks for your help.
