objective c - CGContext Erase Error -


i keep getting error:

my program doesn't call method directly, , frustratingly, can't find documentation on function.

this happens blank (cocoa) xcode project. why getting error?

i had problem. caused outdated wacom tablet driver. if have such driver installed i'd recommend removing it, reinstalling more recent driver. did trick me.
