THREE.WebGLState: DOMException

Error message

THREE.WebGLState: DOMException: Failed to execute 'texImage2D' on 'WebGL2RenderingContext': Tainted canvases may not be loaded.

Cause

Some background animations, which can be found at the slider settings and at the slide settings too, like the 'Morph' or 'Distortion' animations are using different codes from the other animations. These aren't compatible with images that are loaded in special ways, for example Optimole plugin loaded images cannot work with them.

Solution

Either don't use optimization plugin created special loadings on your slider images, or don't use those background animations where you see this problem.
