            Bug ID: 228138
           Summary: wide gamut colors in Web content not shown after
                    moving window from sRGB to Display P3 display unless
                    next repaint
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

Assuming this is a WebKit bug.  STR:

1. Have a machine with two displays, one Display P3 and the other sRGB.
2. Open a new Safari window on the sRGB display and load the attached test.  Notice the two red rectangles are the same color.
3. Move the window to the Display P3 display.  Notice the two rectangles are still the same color.
4. Press Cmd+R.  Notice the two rectangles are now different colors.

Forcing a repaint of the document also makes the display-p3 color show up correctly.
