Okay so this apparantly only happens when you are reading a thread, not within the user's profile. It might be only my...browser but most likely not. (using Chrome)

Open this and another application or just your desktop half-half and see how your whole screen flickers from time to time.

This is not the first time I encounter this, but can't remember the other sigs causing it.

Also, only happens when the signature is 100% visible on the screen. If you scroll half-way through it it's not flickering @J_S
