Flicker black lines on runway/apron surfaces

[undctiatc]

Hello all,

Been awhile and I just reloaded DCS a10. I started up the game and almost had to shut it down as soon as I got in the cockpit. There are little black lines flickering all over the runway and apron surfaces. I have an Nvidea GTX780 with the latest update. No other textures flicker or have any deformity. just runway and apron.

 

Thanks for any help.
