HUD/graphical glitches occurring after prolonged playtime

Hi,

I thought it might be worth mentioning that after playing for a while I started to notice graphical and HUD glitches. Here are what I saw listed from the most annoying to least annoying:

• When I do a Stunt challenge, a lot of the time the target icon that appears to show you where you'll land gets stuck under me when I'm outside of the mission. It's present when I'm walking, jumping from walking, and jumping from boarding. It isn't present though when I'm just rolling around on the board.
• Earlier on in my play sessions the 'Return to marker' direction got stuck on screen after a mission for my whole play session. 
• After about 3 hours of play, the black roads in the game all seemed to lose their textures

I hope this is helpful, because this game has potential to be fantastic.

I didn't get screenshots, but I will if I see them again.

Thanks to whoever this reaches.
