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.)
