virt-viewer-9.0/src/virt-viewer-display-vte.c:189: effectively_constant: Local variable "scroll" is assigned only once, to a constant value, making it effectively constant throughout its scope. If this is not the intent, examine the logic to see if there is a missing assignment that would make "scroll" not remain constant.
