It has been a while since I first reported this problem and, quite frankly, it would be a shame if NT 7 goes into production release while this issue remained unresolved. As it stands, it is hard to justify using NT for making discretionary trading decisions.
As a recap, look at a new example of this problem, now using trendlines on the RSI: The first screenshot (normal view in a two-panel chart) shows a trendline that is not crossed by the RSI in October while the second one (maximised RSI panel) shows one that is cut by the indicator at around that time. Which one is the correct one?

Of course I could figure it out myself by doing an extrapolation, but that is a waste of invaluable time (and may lead to errors) while trading and monitoring many markets. And, as Bertrand suggested earlier, I could temporarily draw the lines using X-axis coordinates which are more distant to each other. However, strictly speaking, I cannot choose where to draw a line. That is determined by market action itself.
The difference between one picture and the other is the difference between putting a trade or not putting it. This additional level of uncertainty should not exist.
Thanks for looking into this again,
Stopped
