I have a laptop that was working fine, and then I updated the video card drivers and all of a sudden there are no lighting visuals. No teleport visuals, no exit/entrance highlight lights, no DF exit point visuals, no bonfires, etc. Example below with exit orbs.

The laptop is set on High Graphics (laptop). Video card is ATI Mobility Radeon HD 4530. Tried restarting, etc.

Any ideas?
