rendered svg in the chrome
Hi! We found the problem with drawing SVG images on canvas. It happens with the experimental flag "GPU Process: Canvas rendering" which is set up by default.
Seems like the new version of Safari with this flag rasterizes SVG before applying canvas context transformation. An example is here https://codepen.io/nikitindev/pen/GRvKmYo
This code works fine in the latest Chrome and in Safari 14 (with default settings), but in the Safari 15 rendered SVG gets blurred.
