Earlier in the month, ArenaNet introduced a new culling method in WvW in to reduce the amount of invisible enemies on your screen. Habib Loew now reports that the trial has been completed and the original culling behavior has been restored:
If you have feedback regarding the trial, or if you have feedback regarding our switch back to the old method, please leave that feedback in this thread. Also, if you’re reporting issues regarding invisible players please include a screenshot of your experience (including mini-map) and your basic system specs (memory, cpu, video card) so that we can more clearly understand the issues you are reporting. We will use this feedback, along with the feedback from the original culling trial thread, to determine if we will switch to the new system until our more comprehensive solution is ready.
I’d also like to reiterate that the system that we were testing is a proposed temporary, interim solution. Work is continuing on a more comprehensive solution to the culling issues and this interim solution has not taken resources away from that effort.
Thank you again for your feedback regarding culling! [Source]
