  Message : Disable compute shader tests on Intel The compute shader tests in angle_end2end_tests fail on Intel Linux. The patch disables the tests for Intel. TEST=angle_end2end_tests BUG=angleproject:1483 Change-Id: I303f0852ea3ccb65c1dd96a196a640c76cc519e4 Reviewed-on: https://chromium-review.googlesource.com/377318 Reviewed-by: Olli Etuaho <oetuaho@nvidia.com> Reviewed-by: Geoff Lang <geofflang@chromium.org> Commit-Queue: Olli Etuaho <oetuaho@nvidia.com> Commit-Queue: Geoff Lang <geofflang@chromium.org>
