I am running into a strange issue with the I/O graph in Wireshark Version
1.10.7.

It seems to be graphing the tcp.window_size with the value of the
tcp.window_size_value.  Below I compared the window size graph in Opnet to
show how the I/O graph is incorrect. tcp.window_size is supposed to be the
calculated value of the scaled TCP window but the actual value in the packet
field.

Has anyone else ran into this ?

Yes.  I've seen it when the capture does NOT have the initial syn
syn/ack & so wireshark doesn't know the window scale factor.
