Web Browser component is flickering (Smart Client)

I’m trying to use C# web browser component on camera view is Smart Client, put each time when I would like to use it, it is not visible or it is flickering. Need assistance with that. Using Visual Studio, plugin runs on Smart Client. Code uses pattern explained in this topic: https://developer.milestonesys.com/s/question/0D53X00005yOBcRSAW/get-camera-name-and-logged-user-name-plugin-development-for-smart-client

Overlay or ActiveElements cannot be use for things like a browser, use only small graphical elements.
