Neon lights
 

The patch updated automaticaly through Steam. Was excited to try to fly after work. Get home , crank it up and now I get neon lights around the instruments and around the markings in the external views. Worked like a champ prior. Plus noticed delay in response to control input that was not there before. WTF....

Check if your anti epilepsy filter is on in the graphics options, it's known to cause brightly coloured anomalies with this latest patch.
