Entities seen through warpzones flicker
Players and projectiles (probably all entities?) sometimes flicker when seen through warpzones. I don't know what is causing it, but it seems to depend on the position of the camera only. Moving to a slightly different spot fixes flickering. Moving the player that is flickering doesn't seem to have any effect.
It might actually be a server side or networking related bug because the flickering seems to correspond with spikes in the network graph (see video). It's really annoying on maps with big warpzones.
Here's a video that shows the bug: http://s.nxs.re/warpzoneflicker.mp4
