Skia analytic coverage depends on framebuffer dimensions as well as raster origin. Replay existing retained subtree pictures into the live viewport at settlement, while preserving overscan images for navigation. Keep settlement pending until the viewport pass and report the presentation path accurately. No additional viewport cache is allocated.
Preserve exact held/released assertions and cover odd/even/fractional pans at DPR 1, 1.25, 1.5 and 2. Verify native picture and backing identity reuse; update one pixel in the existing baseline only after proving equality with direct rendering.
Validation: full check, 735 scoped unit tests, and 58 targeted browser tests pass. The targeted set still excludes the previously classified paint-field-width baseline. An additional tiled large-blur test fails identically on parent d16400b3e, with byte-identical actual PNGs. Broader release acceptance remains separate.
Unify preview-aware transforms across scene drawing, labels, selection and input. Give live property and creation edits explicit preview ownership, preserve cancellation and one-step undo, and reuse bounded text preparation resources.
Include retained device-grid handling, worktree HMR coverage, and nested/reflected interaction regressions in this cohesive progress checkpoint.
Validation: full check passes; 734 scoped unit tests and 53 targeted browser tests pass. This is NOT merge-ready: the unchanged exact nested filled-section held/released regression still fails with 63 differing pixels (maximum channel delta 5/255). The browser pass count excludes that separately run failure and the previously classified paint-field-width baseline. Raster-origin investigation and broader acceptance remain outstanding.
- Warn once with the rejected surface dimensions and original CanvasKit error
- Disable repeated cache allocation attempts until the renderer surface is replaced
- Keep direct scene rendering as the visible fallback
- Scale retained margins to a fixed device-pixel budget on large viewports
- Fall back to direct scene rendering when CanvasKit rejects an offscreen surface
- Cover the reported wide HiDPI geometry without coupling rendering to a WebGL context
- Fall back to live rendering when CanvasKit cannot allocate the backing surface
- Match retained backing metadata against the current graph preview version
- Cover null-surface and stale-preview backing regressions
