Since the patch 10.2 hit today
Any kind of procc that would normally be indicated with a glow around the actionbar button, does not work if that button is a macro.
even a simple macro like:
#showtooltip
/cast X

This have always worked as you would expect up untill the 10.2 patch hit today.
my specific case is a Enveloping mist macro, where as after 3 kicks when Chi-ji is up, my Enveloping mist becomes instant cast and usually glows, indicating its instant cast.
The macro i use and have used:
#showtooltip
/cast [target=mouseover,exists] Enveloping Mist; Enveloping Mist

• so just a simple macro, nothing weird about the macro itself, this problem stems from Bartender4.

/Armleg

This should be fixed in the upcoming update

Same issue here. None of my macros glow since 10.2. The button glow on macros still works normally on the default UI, so it does indeed seem to be a problem with Bartender.
