To resolve this use an 17image diffing tool like Beyond Compare and visually check differences between 18the unknown image and older versions. 19Note: it should nearly never be required to remove old versions of good/bad 20images from these directories. 21""" 22ATTRIBUTES = "suite:hwqual" 23TIME='FAST' 24TEST_CATEGORY = 'Performance' 25TEST_CLASS = "gl" 26TEST_TYPE = 'client' 27BUG_TEMPLATE = { 28 'components': ['OS>Kernel>Graphics'], 29} 30 31DOC = """ 32On hwqual we do not upload performance numbers to the chrome dashboard.
