strange thing appears on my screen

[apr1cot]

i've recently returned to sl, i'm using firestorm and it was completely normal before but now when i look at some avatars, my screen looks like this, i look away and it's normal again. This only happens when some avatars appears in my view. Does anyone know what this is?

sorry for my English btw

I haven't seen this happen for a while. Have you checked your graphics card drivers are updated to the latest version?  And ensure you are using the latest viewer for Firestorm.
