Ticking screen error

[Mathias351]

I get a ticking screen error message whenever I attempt to connect to a friends LAN server. I have updated my java, but still no luck. I can play single player just fine, but this happens every time I try to connect. Another friend is able to connect just fine.

Here's the error report:
