Black, horizontal lines appear when scrolling in text websites
On several computers on the network, thick black lines randomly appear when you scroll. To get rid of them, you have to scroll to another part of the page. I have tried tweaking the graphics acceleration, updating all parts of Firefox, and am running with no add-ons. All the computers are running Windows 7 on newly updated RAM and video cards, on new-ish monitors.

You can try to disable hardware acceleration in Firefox (you need to close and restart Firefox).
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
