Hi,
I am on build 3080 (mac)
1 - changing the font-size via apple+/- is really (5+secs) slow at least the first time you do it. (it seems to cache by font-size)
2 - also changing the font-size only seems to affect the global font size not syntax-specific font-size (if you have one).
I would think that if you change font-size while viewing a file where you have a syntax specific setting then that is the setting to be changed.
For me this is a little painful b/c I often need to deal with chinese text (which I often need to magnify greatly in order read) but then return to non-chinese code which can be viewed using much smaller font-sizes.
Thanks.
