winit 0.30 delivers no file drops on native Wayland. The new Linux Display Server preference (Automatic / X11 (XWayland), shown on Linux only, read at startup) has winit open the window on X11 when the session is Wayland, DISPLAY is set and the X11 libraries winit loads are installed (ldconfig check ported from PhotoCraft); otherwise the window opens on Wayland and the log says why. README, development notes, parity docs, ROADMAP and the complete catalogs updated. Co-Authored-By: Claude Opus 5.5 <[email protected]>

Hardware parity
Last reviewed: 2026-10-10 · Last updated: 2026-10-11 · Change: minor (Linux Display Server preference opens the window through XWayland, #1151) · Target: Adobe Illustrator 2026 (30.x)
What hardware Illustrator uses, per platform, against VectorCraft. Illustrator's side is from its public
documentation (GPU Performance, touch workspace, pen pressure pages); ours from the code
(crates/ui-egui/src/canvas.rs, touch.rs, graphics.rs, crates/render). Part of
target-app-parity.md.
Summary
~35% (estimated), 25–45 h. VectorCraft rasterizes the canvas on the CPU (multithreaded vello_cpu) and uses
the GPU only to composite, so any GPU that can show a window works, at the cost of GPU-accelerated preview
on huge documents. Pen input is pressure-only and Windows-first.
| Feature | Illustrator | VectorCraft macOS | Windows | Linux | Web | Status / hours |
|---|---|---|---|---|---|---|
| GPU-accelerated canvas (GPU Performance, GPU Preview, GPU anti-aliasing) | Metal, DirectX | CPU raster, GPU composite (wgpu/Metal) | CPU raster, GPU composite (DX12, OpenGL fallback) | CPU raster, GPU composite (Vulkan/GL) | WebGPU, WebGL2 fallback | partial; a GPU renderer spike is pending (M5): 15–25 h |
| Multithreaded rendering off the UI thread | partial | yes | yes | yes | single-threaded | beyond Illustrator |
| Hybrid-graphics GPU choice | automatic | power-saving GPU by default, Preferences › Graphics Processor | same; DX12 then OpenGL; no Vulkan unless asked (#545, #806) | the desktop's GPU | browser | done |
| Restart on another GPU when the first fails to present | — | yes (#502, #964) | yes | yes | restart on lost device (#369) | done |
| Pen pressure | yes (Wacom, Windows Ink, macOS tablet events) | no (winit reports none, #852) | yes (pointer force via WM_POINTER) |
X11 only via XWayland (Preferences › Performance › Linux Display Server, #1151); none on Wayland (#491, #764) | browser pointer events | partial: 4–8 h for macOS and Wayland (winit 0.31) |
| Pen tilt, bearing, barrel rotation (6D Art Pen) | yes, drives brushes | no | no | no | no | missing: 4–8 h after the input layer (#372) |
| Pen eraser end | yes | no | no | no | no | missing |
| Touch gestures (pinch zoom, two-finger pan, rotate view, Touch workspace) | yes (Windows touch, Surface) | trackpad pinch and scroll | pinch, pan; two-finger tap undo, three-finger redo (#585) | same where winit reports touch | same | partial: touch workspace and rotate gesture missing, 3–5 h |
| Trackpad (smooth scroll, pinch) | yes | yes | precision touchpads | yes | yes | done |
| HiDPI / Retina, per-monitor scale | yes | yes | yes | yes | yes | done |
| Multiple monitors: panels and document windows on another screen | yes | no (one OS window) | no | no | — | missing: 6–10 h (with multiple windows, gap G7) |
| Display colour profile (proof and display through the monitor's ICC) | yes | no | no | no | — | missing: 3–5 h |
| 3D GPU rendering (Materials, ray tracing) | yes | — | — | — | — | blocked on 3D (gap G3) |
