CE crashes on machines with ATI graphics cards

Dear all.

There's a bug in the ATI graphics driver which crashes the driver, which crashes CityEngie when handling textures with certain very special image resolution ratios.

The crash only occurs when both 'MipMapping' and 'Texture Compression' Rendering options are active, which is the default in CityEngine.

Deactivating one of those 2 options will prevent the crash.

Find them under : Preferences > General > GrammarCore

Since deactivating the Texture Compression will be problematic with datasets that contain many textures, we recommend to deactivate the MipMaps since it only results in a very marginal flickering of the textures in the viewport.
