Issue detected : The 2D view has a black patch on it
Cause of the issue : This is a known issue, it appears mostly for those having Nvidia graphic card in their computer.
We suspect that the latest drivers of the graphic card are conflicting with Artlantis and causing the black patch on the 2D window.
How to solve it : Until this bug will be fixed, we suggest you to downgrade your graphic card driver if possible. Please set back to a driver released in September 2017 or earlier.
