How do I keep the canvas pixel-snapped on a 4K monitor?

Lior Dahan

Setup: 27" 4K display, scaled to 175% in macOS, latest CorriDraw web build.

When I drag a rectangle the position jitters by a fraction of a pixel as I move it — so the rectangle's edge looks fuzzy on export. Other tools (Figma, Sketch) snap cleanly. Is there a setting I'm missing?

I tried turning on Snap to grid in the View menu but that snaps to the 8-px grid, not to integer pixels.

Two things help here:
1. View → Pixel snap (currently behind the Canvas v2 feature flag in Settings → Labs). Once it's on, dragging snaps to the nearest device pixel regardless of zoom level.
2. The fuzziness on export is a separate issue — it's the SVG rasteriser using subpixel anti-aliasing. If you export to PNG with the Crisp edges option enabled (Export → PNG → Advanced), the edges land on the pixel grid.
Pixel snap leaves the Labs flag and ships to everyone in next week's release, which is why it's front-and-centre in the roadmap thread.

That fixed it. Both things. Crisp edges is the export setting I was missing. Thank you.

Adding to this — if you also have an external monitor at 1.0x scale, the same export still looks crisp because Crisp edges measures the device pixel grid, not the OS scale factor. Saved me when I plugged into a projector for a customer demo.
