Screen Artifacts on my Advent Vega

---

Hello, I bought an Avent Vega Tablet and I've been using it for a couple of weeks, but now I've noticed artifacts on the screen while using it. They are like black flickering lines. Does anyone know if this is a hardware or software problem. It does it most of the time when surfing or gaming. I'm using the Dolphin Browser and playing games such as Fritz chess and there's black flickering lines all over the screen. Most of the time they temporarily disappear if I press the home screen and go back into the app, but they eventually come back again. Maybe it's just a gpu driver problem. Any ideas what the cause might be? Overheating?

Thanks!

Welcome to xda dev, i notice this is your first post

It is a gpu driver issue. Has been always been there. What rom are you running, v1.09 is better than v1.08.

Thanks!

Hi ganjaman, I'm also running Rom 1.09. So are there any new drivers available that fixes the problem?

Not that i am aware of at the moment.

Ok thanks. I'll probably try reflashing it. Hopefully that will fix the problem.

Flash it as many times as you like, it will not fix the artifacts.

PEACE!!
