I was observing 1.9ß3 and the lag issue in WSG tonight. It seems that
when a new member is added, PerfectRaid adds it to the list, then it
redos its list to sort it by the sort order specificed by the
PerfectRaid configuration. This seems to make it so that XUB creates
the buttons, then when persons are moved around in the raid, deletes
and recreates the buttons when PerfectRaid is done moving things
around. If this is happening when you are away from everybody,
there's a one to three second freezing of the screen. However if this
happens when you are in the midst of things with buttons enabling/
disabling and dimming (range checks, OOM issues, etc.) the lag can
take up to fifteen or more seconds.
I tried working with the "wait to update" slider for raid issues,
thinking if I just increased the rate XUB wouldn't try doing its thing
until PerfectRaid was done moving things around, but that didn't seem
to eliminate the lag for some reason! /scratches head
Anyway, some info on the subject, for what its worth. I would suggest
that the ticket be reopened though, as it was closed (or marked as
fixed?).
