As of Chrome 86, the image editing tab no longer displayed the image. Upon review, we discovered that a Chrome feature related to using an available GPU was affecting the <canvas> tag and was causing the issue. The rending of a drawable canvas on top of a background image was obscuring the image, even though the canvas element had an opacity setting.
This new Chrome function does not appear to be causing issues with mobile versions or server versions of Chrome. However, many PC's have GPU's and are affected. To fix this, you must turn off the Chrome feature.
Go to chrome://flags
Search for or locate the Accelerated 2D canvas setting, and ensure it is Disabled.
