I have problem with RU on windows some 10 machines. When I open Google Chrome or Firefox I can't see what is in browser. I can see only white blank window, without any content.
Browsers are running and visible on host's monitor. Clicking on upper right angle of white window closes browser but close button isn't visible too. This problem does't apply to MS Edge.

I'm using legacy capture mode, with legacy capture mode turned off I can't see anything on remote screen (everything is black).

How to fix this?

Hello Djordje,

Thank you for your message.

Please try enabling the Capture alpha-blending windows feature. To enable it, right-click on the remote connection in the address book and select Properties. Then navigate to the Additional Properties tab and tick the Capture alpha-blending windows checkbox:

Hijacking the thread since I'm having this same problem. When I start the remote session screen is just blank (black) and only thing that fixes this is to set legacy capture mode on in host settings. After this all seems to work fine excep tfirefox window is blank (white) and I can't get it to work (unless i disable hardware acceleration which i wouldn't want to do). Setting alpha-blending capture does not affect this..
Both host and client are windows 10 latest version. Host is running on Nvidia gpu. Is there anything else that could solve the problem other than disabling H-A?

I till today didn't found a way what causes black screens and windows and how to fix that. Using legacy capture mode is only solution for now.

Hello Jukk,

Thank you for your message.

Like viss02 has stated above, unfortunately, using the Legacy capture mode indeed is the only solution that might help to resolve such issues.

Please let us know if you have other questions.
