Package: tigervnc-scraping-server
Version: 1.9.0+dfsg-3
Seems the tigervnc package is missing randr support.

Geometry: Desktop geometry is set to 1024x768+0+0

While my system/X server certainly has the RANDR extension:
==
$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 7680 x 7680
HDMI-1 connected primary 1024x768+0+0 (normal left inverted right x axis
y axis) 0mm x 0mm
1024x768 60.00*
800x600 60.32 56.25
848x480 60.00

Think you are missing a build dependeny on the libxrandr2 library.
If HAVE_XRANDR is not set at compile time, it always prints the message
