[Interest] Window ID of the current screen (root window)?

[Richard Moore]

Digging back through the code, I can see that the XCB platform plugin
ensures that the Display * and the xcb_connection correspond to the same
display by opening them together using the same string (in Qt 5). Assuming
the same is done in the Qt 6 plugin then exposing them again through
QX11Info would be just the same as in Qt 5.

Cheers

Rich
