Hello there,
Referencing this post: https://forums.nomachine.com/topic/white-black-transparent-screens-on-certain-apps-windows10
I have the same issue… certain windows, for example Radeon Software, appear transparent, although a border can be seen and buttons pushed (if you know the general location), it’s not possible to actually see anything.
The server I’m connecting to is headless, but when a monitor is connected and turned on it appears to function properly.
I’ve disabled hardware encoding and acceleration, but thus far no joy.
Any ideas?
