Enabling / disabling the scrollbar in the profile causes column numbers to be off

[primis]

Expected behaviour

After editing a live profile's scrollbar visibility, the character grid dimension tooltip should show the correct number of columns visible on screen.

Actual behaviour

After editing a live profile's scrollbar visibility, the character grid dimension tooltip will be +/- 2 columns of truth depending if the bar was added or removed (see screenshots).

Steps to reproduce the behaviour

Open a terminal, edit the profile of the active terminal to either remove or add the scrollbar (Whatever would be opposite of currently active setting). At which point attempt to resize the window by it's edge. The tooltip showing the lines and column size of the current window will be off from what is actually shown. Any subsequently opened new windows do not have this issue.
