Created attachment 355246 [details] attached html and checker.png image that shows pixelated works for the img but not canvas I am trying to turn off antialiasing for a WebGL context inside Safari and cannot do so. Attached is an HTML file that can reproduce this problem, it works just fine on Chrome and FireFox. This example simply opens a WebGL context and draws a rectangle. The output in Safari has the edges antialiased, which it should not. Either this is a bug, or I am missing something that I should be doing that is specific to Safari/Webkit? Please let me know if either way. I set the "antialias" option to false that is passed into glCanvas.getContext("webgl", options);, and I also use the style flags that I have found resources on the web/stackoverflow that normally turns antialiasing off. The exact versions I am using are Safari Version 12.0.1 (13606.2.104.1.2) on OSX 10.13.6. Thanks! Blaine
