The texture bug occurs on both advanced and normal monitors. It shows vertikal and horizontal white stripes.

A similar effect can be seen when Monitors form connected Textures:

I've searched google for quite a while and couldn't find a similar bug.
This texture bug is very annoying as it makes reading of monitors very uncomfortable.
