@Aidaknow, @TungstenMD - I've created a tool (still beta version), that automates workaround mentioned above. It triggers whenever Windows background changes, takes a snippet of current background, and saves it to a file (you'll setup Aida64 to use this file as panel background and It'll automatically reload it's background whenever said file changes).
There's a lot to be improved, but it works as-is for me in Windows 8.1 (edit: works with Windows 10 as well)
I plan on preparing some more detailed description, and improving this tool, but since it might be hard for me to find some time
