I'm using Xlib for my application and would like get image from root window
I open separated Xserver in another tty (:1) then opened this diplay
XGetDisplay(":1")
I'm working in :0 display
After I get default screen and root window and want to get image of this root window
Unfortunately I've got only black screen if my window is hidden
Can I someway force X11 to render window if it's hidden?

When not visible on screen X11 windows don't have to keep their surface pixmaps. You can force this with Composite extension, NameWindowPixmap request
