 // This file contains a list of defective khronos_glcts conformance tests. The
 // expected format is:
 //  {BUG#} {MODIFIERS} : {TEST_NAME} = {PASS,FAIL,FLAKY,TIMEOUT,SKIP}
 //
 // MODIFIERS can be a combination of the below list:
 //  WIN XP VISTA WIN7 MAC LEOPARD SNOWLEOPARD LION LINUX CHROMEOS MOUNTAINLION
 //  MAVERICKS
 //  NVIDIA AMD INTEL
 //  0xabcd - GPU PCI device ID. Specifying a PCI id requires a vendor.
 //  DEBUG RELEASE
 //
 // TEST_NAME can be a specific test name, or have a '*' in the end, which
 // indicates a prefix matching.
 //
 // Any tests whose expectations are not PASS will be skipped on the bots.
 //
 // Examples:
 //  91530 MAC WIN LINUX : context_lost_restored = TIMEOUT
 //  91533 WIN : gl_min_uniforms = FAIL
 //  91531 MAC WIN LINUX : conformance_more_* = SKIP
 //  91532 MAC NVIDIA 0x0640 : tex_image_and_sub_image_2d_with_video = PASS FAIL
 
 // Chromium implements GL_ARB_texture_rectangle which makes this test fail
 139729 DEBUG RELEASE : ES2_CTS_gtf_GL_build_Texture_Rectangle_Samplers_frag = FAIL
 
+// eglGetCurrentDisplay() returns EGL_NO_DISPLAY which causes this test to fail.
+421568 DEBUG RELEASE : ES2_CTS_gtf_GL2ExtensionTests_egl_create_context_egl_create_context = FAIL
