When I start my computer all appears fine. I can navigate all menus. When I open terminal/ terminal programs they look fine until I go to use them or move them. It also happens when opening multiple terminals. Thought it might be memory but I have 4 gig.

Also, I used the the same CD to install kali on my other PC and it works great, so not a bad OS install.

The problem persists whether using live or full install of the OS.
