You may encounter this error if Explain Everything isn't able to use your computer's graphics card in order to display the contents of your canvas. The app will instead use software mode, which means some elements may not display properly.
If none of the listed methods work, this probably means that your graphics card does not support the technology required for hardware acceleration and Explain Everything will run only in software mode.
Try using a different browser or update the one you're using
Sometimes your hardware might not work properly with the browser you are using. Here's a list of links to supported browsers.
NOTE: If you are using Chrome or Opera, please try Firefox or Safari instead.
Chrome browser - enable hardware acceleration
If you are using Google Chrome, please make sure that the Use hardware acceleration when available option is enabled.
- In your Chrome browser open the ⋮ Menu next to the address bar.
- Select Settings.
- In the search field, enter "Use hardware acceleration when available"
- Set the setting to ON.
Update your graphics card drivers
