I have had the same problem here.
I do not know when it started exactly (it wasn't the when I first installed Ubuntu but suddenly some websites (like google maps) started to display half maps. Then I was able to pinpoint to a problem with wireshark.
First I added the line "net.ipv4.tcp_window_scaling = 0" to sysctl. the was better but not gone. Then I also added net.ipv4.tcp_wmem = 4096 16384 131072 and net.ipv4.tcp_rmem = 4096 87380 174760. Now all is forking fine again.

If it helps I can put requested info below, just let me know what I can do.

What is of more interest was that Wireshark saw tcp checksum errors. The exact message was
"Checksum: 0xaa59 [incorrect, should be 0x2035 (maybe caused by "TCP checksum offload"?)".

That is gone now.
