@prsadhuk I have changed the test case to explicitly set the table and header background to white. Mach5 tests are passing on all platforms including linux now. Can you please let me know in case you are seeing any issues on Ubuntu locally, with the new test case? In order to mark the test as mac only should we specify it this way - `@requires (os.family=="mac") ` in jtreg tag section?
