    Message : Skip more tests on Linux AMD RX 5500 XT Remove EGLFeatureControlTest suppression, which crashed due to calling IsVulkan() without an initialized context. angle_perftests: MultisampledRenderToTextureBenchmark.Run/vulkan_multipass_ds angle_white_box_tests: VulkanPerformanceCounterTest.RenderToTextureDepthStencilRenderbufferShouldNotLoad Bug: chromium:1004356, angleproject:5380, chromium:1097750 Change-Id: I38819374242b71fb57c54a9d0fb47b1547dda895 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2556445 Reviewed-by: Yuly Novikov <ynovikov@chromium.org> Commit-Queue: Yuly Novikov <ynovikov@chromium.org>
