2. Update your drivers to resolve any driver compatibility issues. That may include your graphic card, motherboard, Bios etc.
3. Reset in-game options in Blizzard app (Settings -> Game Settings).
4. Try closing background applications to resolve any software conflicts.
5. Uninstall and reinstall the game you are having issues with.
6. For Windows OS: An outdated or incorrect DirectX installation may trigger this error. Reinstall DirectX using Microsoft's web installer.
