Aye. And it is the only addon that causes it. Looks like lag (similar to high latencies) but both world and home latencies are in the 25ms range (as they always have been). Seems strange, but it did only appear after updating to 2.0.1. When OQ is enabled, it doesn't occur right away - takes about 10-15 minutes before it starts to appear. But after logging out and disabling OQ and logging back in the issue is resolved and doesn't return regardless of how many hours I'm on.
Weird huh?
