Comment 3 for bug 110442

well I have the same problem, except mine are white lines. I am using an ATI Radeon 9550 with the proprietary drivers installed from synaptic. as for step by step instructions I just open my email and view a message. The fact that he probably left out though is that it happens in the windows Live mail which I have been using since the beta. the classic view (as they call it) doesn't have this problem. let me know what commands output you need or any other info and I will be glad to provide it
