Guild Wars 2

I have a problem with blue lines appearing and flashing as I’m moving around. As well as random terrain appearing in places, such as boulders, and ladders..etc.
I checked my drivers and they are all up to date, the game runs smoothly, i have no issues there.
I set it to virticle sync in the game menu but that didn’t help at all, i don’t know what to do.

I have an Acer aspire 5750 laptop
Intel HD graphics 3000.
8gb DDR3 memory
1000gb hdd
I dont know if this information helps.
