Problem with transparency in 3D view in chrome

Looks like a Chrome bug, not sure if there is anything we can do on GeoGebra end to prevent this.

It would be helpful if users who experience this could tell us what system they use (OS version + Chrome version + grpahics card) so that we can file a bug for Chrome.

To get the required info go to:

chrome://gpu

then "Save as..." -> "Web Page, Complete"

Sooo many informations! May be ...

• WebGL: Hardware accelerated but at reduced performance
• WebGL2: Unavailable

Note: To properly save this page, select the "Webpage, Complete" option in the Save File dialog.
