What's up with CGContext errors?

[Jamie]

Not a bug but I don't know where else to ask this. (Running BfW 1.10.5 on Intel Mac OS 10.6.8)

I have been working on some old UMC and want to debug. I just tried removing *all* the add-on campaigns (and deleting the cache) thinking I would move only one campaign into the add-ons folder at a time to better help locate problems and then launched wesnoth from Terminal. So with only mainline content loading, I am still getting a raft of CGContext errors. This doesn't hurt anything... the game runs and plays just fine. But if there's a simple way to eliminate them, I would love to know just to keep the list of errors I have to wade through to a minimum. I've spent several hours searching the web and reading Apple's Quartz 2D reference material. I understand this may be a quirk of the Mac port or otherwise something buried deep in C++ code that's not worth chasing down. I'm asking just in case there's some relatively simple configuration tweak I can make to get rid of them.

Examples:
...-iMac.local Wesnoth[6918] <Error>: CGContextSetFont: invalid context 0x0
...-iMac.local Wesnoth[6918] <Error>: CGContextSetFontSize: invalid context 0x0
...-iMac.local Wesnoth[6918] <Error>: CGContextSetTextMatrix: invalid context 0x0
...-iMac.local Wesnoth[6918] <Error>: CGContextClearRect: invalid context 0x0
...-iMac.local Wesnoth[6918] <Error>: CGContextSetRGBFillColor: invalid context 0x0
...-iMac.local Wesnoth[6918] <Error>: CGContextShowGlyphsAtPoint: invalid context 0x0
...-iMac.local Wesnoth[6918] <Error>: CGContextSetFont: invalid context 0x0
etc...

I confirm the same problem on a macbook air OSX 10.8.3

plus Wesnoth use ALWAYS a lot of CPU. I read around and I could not find a way to stop it

[denix]

Ok, solved the high cpu use:

Thanks for your input, denix.
