  "message": "Fix MSAARenderToSingleSampled in Graphite/Dawn\n\nThe MSAARenderToSingleSampled feature was recently implemented in\nDawn/Vulkan. The current implementation in Skia isn\u0027t compatible with\nthe restrictions of the feature in Dawn. This triggers validation errors\nthat break Graphite/Dawn/Vulkan.\n\nDawn enforces that depth/stencil samples must match the sample count\nspecified for a render pass. This is because Dawn never supported\nresolving depth/stencil attachments. Graphite was using 1x depth/stencil\nattachment when render pass was rendered at 4x because the Vulkan\nextension supports that. Change Graphite so depth/stencil sample count\nalways matches the render pass sample count. Note this also applies to\nGraphite/Vulkan when VK_EXT_multisampled_render_to_single_sampled is\nused.\n\nAlso update the dawn struct used with MSAARenderToSingleSampled.\nwgpu::DawnRenderPassSampleCount is the new struct and it\u0027s chained on\nthe render pass instead of color attachment.\n\nBug: chromium:482088881\nChange-Id: If5bb8c78bbe65bb7f8487089380c732daaed41c0\nReviewed-on: https://skia-review.googlesource.com/c/skia/+/1157378\nReviewed-by: Michael Ludwig \u003cmichaelludwig@google.com\u003e\nCommit-Queue: Kyle Charbonneau \u003ckylechar@google.com\u003e\n",
