I’m on a Mac and I think the latency bug is preventing the safezone from showing up. However I used oUF 1.5.15’s castbar.lua and the safezone is showing up again (but latency is still 0). This castbar safezone works with Mono UI and Shestak UI (I haven’t tried it with others).

Thanks.

They are most likely overriding the default oUF behavior, to use the
GetTime() method of implementing a safe zone.

I could make oUF use GetTime() instead of GetNetStats(). The main
issue is really that the GetTime() method will easily spike and give
horribly incorrect return values, while GetNetStats() returns a more
average over time latency.

I appreciate the explanation, thanks. 1.5.15 currently works for me so no need to change anything with the current release.
