To resolve this use an 16image diffing tool like Beyond Compare and visually check differences between 17the unknown image and older versions. 18Note: it should nearly never be required to remove old versions of good/bad 19images from these directories. 20""" 21ATTRIBUTES = "suite:hwqual" 22TIME='FAST' 23TEST_CATEGORY = 'Performance' 24TEST_CLASS = "gl" 25TEST_TYPE = 'client' 26BUG_TEMPLATE = { 27 'components': ['OS>Kernel>Graphics'], 28} 29 30DOC = """ 31On hwqual we do not upload performance numbers to the chrome dashboard.
