3D graphics view using Chrome has ugly blue background
I just tried to upload an example displaying 3D Graphics view, and an ugly blue background was displayed in Google Chrome (and Safari). I made a GeoGebraTube search and all 3D-examples displayed the same ugly blue background. Then I found an old applet I made where I (apparently) wrote a comment (to myself) about this.
The worksheets all look good if using Firefox but not Chrome and Safari, at least if using a Mac.
