When importing photos on the canvas, they are verry blurry and pixelated at almost every zoom level, except when you zoom very closely. Other tools (Figma, Sketch) handle image resolution much better without blurriness or pixelation.

After looking at it, I can confirm that the “blurry” image is for display purposes only but the actual resolution remains intact. After 28% zoom, Linearity Curve automatically starts displaying a thumbnail, which could be the culprit here. However, when you export, this shouldn’t be the case. Rest assured, the team is looking to refine it for a better display all around.
