Maverics - "CoreText performance note"

[s2krish]

I got following message in console log. My system is MBP Late 2011 (MacBookPro8,1), OS X 10.9

Can you please test this with Sublime Text 3 Build 3047 or Build 3056 if you're a registered user and see if you get the same type of messages? Unfortunately, ST2 bugs are very low on the priority list unless they're extremely serious. While this bug isn't serious, it's more likely to get attention if you can replicate it in ST3.

Thanks!

[s2krish]

Thanks! ST3 also has same bug. May be it is not bug, but just as OS X 10.9 note for performance.

I'm getting the same thing. I was trying to fix a bug with my sublime (it's hanging forever when I open it) and then I saw this... would it be the cause?

[MattDMo]

@bsides If you're on Mavericks, there are a whole bunch of other things that could be happening, and I'd put this issue pretty low on the list. From what I can tell, this is essentially just a warning that "performance could be better" if the API was called in a slightly different way - it doesn't mean that ST is hanging, or even that there's a real serious degradation of performance (although there could be, I'm not familiar with this API).

Personally, I'm staying on Mountain Lion until a whole lot of issues with Mavericks get addressed, including many issues with Python, which is my primary language currently. I might be comfortable with upgrading by 10.9.5 or so :grinning:

You can use "font_face": "Monaco", as "quickhack".
