Linea's 3D view uses WebGPU, and these browsers support it. Keep your browser up to date, because older versions may not.
If your browser does not support WebGPU
Linea shows a notice across the canvas: Rendered views will look flat in this browser. Drawing, modelling and export all work normally. Shaded views lose ambient occlusion and global illumination, so they look flatter. Close the notice with Dismiss and it stays closed in that browser.
If the 3D view does not appear at all
If a browser offers neither WebGPU nor WebGL, the canvas shows 3D viewer unavailable. Switch on hardware acceleration in your browser's settings, then reload the page.
