GPU problems

Hi all, just installed Blender for the first time and having some issues maybe with the graphics card settings? The window resolution has very heavy vertical black lines through it which is making it impossible to see what’s going on. My GPU is an AMD Radeon HD 8570D.
Thanks

This is super weird I think, but I´m not an expert, the weirdest thing is that it´s happenign in 2.79.

Maybe @brecht knows what is happening here.

Cheers!

Feels like a driver issue.

Changing User Preferences > System > Window Draw Method may help.

Also potentially installing the latest graphics drivers, and tweaking/undoing any changes in your graphics driver settings.

Thanks for the suggestions but still no joy I’m afraid.
If it was a driver issue, surely it would affect other programmes?
