I am primarily using the Firefox-based Zen Browser on my Macbook Air.

When using Canva, I noticed that Zen Browser is often displaying design compositions wrongly, misplaced, shifted. When I download/print the designs, everything is correct, so the browser is not messing with the design itself, just how it displays.

When switching to a Chromium-based browser, I do not encounter that issue.

Has anybody experienced the same? Or can reproduce it?
