I am using a MacBook Pro and have this problem in both Safari and Chrome.
When I expand the terminal or log window it uses over 100% of the available windows space. Once I get to the bottom of the window I can’t see the last few lines. Terminal does this all the time, whether it is maximized or not, since it is always situated near the bottom of the browser window. However, the log window only exhibits this problem when maximized.
I don’t think this has always been the case, but I don’t remember when I started noticing it.
I wonder if it is related to the fix of the following issue.
