Thanks, this is helpful. I have some code which calculates the width of the
buffer contents in characters, and calculating this pixelwise works nicely for
me.
The odd thing is that there’s a one character discrepancy between graphical and
terminal frames. It’s not related to the new line numbers support, since an
adjustment for that discrepancy has always been necessary in the code, and the
native line numbers are not present in the terminal anyway. Any idea where that
one-column difference might be coming from?
