Comment on attachment 454109 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=454109&action=review Looks great. A couple of small comments, but r+. > Source/WebCore/platform/graphics/cocoa/GraphicsContextGLCocoa.mm:161 > + // is anyway already powered on. Perhaps mention here that this code relies on the assumption that EGL_ANGLE_platform_angle_device_id uses the IOKit registry ID of the GPU on Mac platforms? > Source/WebCore/platform/graphics/cocoa/GraphicsContextGLCocoa.mm:163 > + displayAttributes.append(EGL_PLATFORM_ANGLE_DEVICE_ID_HIGH_ANGLE); Would you like to at least ASSERT the availability of the EGL_ANGLE_platform_angle_device_id EGL client extension somewhere?
