Greetings, I wanted to inform you all that I landed a change to DumpRenderTree (run-webkit-tests) this evening that affect any of you who run the layout tests with the --pixel option. This change allows us to render color-matched content in a consistent manner across all machines. http://bugzilla.opendarwin.org/show_bug.cgi?id=6155 If you use the --pixel option, you will notice your system colors changing for a while, as well as this see this warning: WARNING: Temporarily changing your system color profile from "My Custom Profile" to "Generic RGB Profile". This allows the WebKit pixel-based regression tests to have consistent color values across all machines. The colors on your screen will change for the duration of the testing. DumpRenderTree is now smart enough to change your system color profile while it runs, and restore it when it quits. If, in the very unlikely event that DumpRenderTree were to crash, it could leave your system with "Generic RGB Profile" as the system color profile. In that unlikely event, you can restore your custom color profile inside System Preferences : Monitors : Colors. Hopefully we'll find an even slicker solution soon. Happy holidays, -eric
