Unity editor visual artifacts

Hey,

I’m experiencing a constant issue with the Unity editor displaying weird visual artifacts when I resize windows in it.
See image:

Resetting Unity solves the issue until I resize the windows again, then it comes back.

I’m on Unity 4.3.4f1 Pro (64-bit), on a HP dv6 laptop with AMD Radeon HD 7690M XT graphics card.

Has anyone else experienced this? can the developers chime in to solve this issue?

Bump…

Can anyone help me with this?
