For what it's worth, I quickly tried to passthrough one of the onboard USB controllers instead (Intel Corporation 82801JD/DO (ICH10 Family), which is also affected by the 4k limitation). It improves the artifact problems, bringing the artifacts down to one artifact every 5 seconds. I'll be back in ~1½ week, please tell me if you want me to test something when I get back.
