Comment #6 on issue 21658 by m...@chromium.org: All webpages are painted white http://code.google.com/p/chromium/issues/detail?id=21658
Based on the log messages, there's a bad CGBitmapContext due to having a bad CGColorSpace, and the CG calls that are failing and the order of the messages points to skia::BitmapPlatformDevice as the caller (skia/ext/bitmap_platform_device_mac.cc). The CGBitmapContexts in there are created using mac_util::GetSystemColorSpace() (base/mac_util.mm), which is new in 4.0.207.0. (Confirm that this is a regression?) We "warm up" mac_util::GetSystemColorSpace() during renderer startup before bringing up the sandbox, but maybe that function is failing for other reasons. If you start Chrome with --no-sandbox, does the problem persist? Can you describe the display configuration a little bit more fully? Color profiles in use? Custom calibrations? Displays disconnected and reconnected since boot? Could you compile (g++ displays.cc -o displays -framework ApplicationServices) and run the attached program, which tries to get some display information? This program goes through the same motions to get the system profile that mac_util::GetSystemColorSpace() does in Chrome, and it also tries a few other things. (I'd try the test program first, while you're still experiencing problems in Chrome, so that you've got a record of it in case checking or playing with any of the other settings "fixes" things for you.)
