Using latest version available, this problem only happens on my Rdruid while the addon is loaded but not in use (healing spec), other specs / classes are ok. It is 100% tied to Hekili (tried every addons one by one). It's a similar type of stutter that when changing a talent on a dps spec.

Basically whenever I mouseover a npc or a player, or a health bar in my groups, my fps drops heavily, independently of if I'm in combat or not. It is ONLY tied to healing specs, as dps specs doesn't seem to have this problem.

Can you provide all the ticket information? Obviously, a snapshot would not apply.

It doesn't seem to be a conflict with another addon, the stutter still happens with only Hekili loaded.

Are you comfortable testing an edit?

In Events.lua, we need to change line 2250; from:

RegisterEvent( "PLAYER_ENTERING_WORLD", ReadKeybindings )
RegisterEvent( "ACTIONBAR_SLOT_CHANGED", ReadKeybindings )
RegisterEvent( "ACTIONBAR_SHOWGRID", ReadKeybindings )
RegisterEvent( "ACTIONBAR_HIDEGRID", ReadKeybindings )
RegisterEvent( "ACTIONBAR_PAGE_CHANGED", ReadKeybindings )
RegisterEvent( "ACTIONBAR_UPDATE_STATE", ReadKeybindings )
RegisterEvent( "SPELL_UPDATE_ICON", ReadKeybindings )
RegisterEvent( "SPELLS_CHANGED", ReadKeybindings )

To:

RegisterEvent( "PLAYER_ENTERING_WORLD", ReadKeybindings )
-- RegisterEvent( "ACTIONBAR_SLOT_CHANGED", ReadKeybindings )
RegisterEvent( "ACTIONBAR_SHOWGRID", ReadKeybindings )
RegisterEvent( "ACTIONBAR_HIDEGRID", ReadKeybindings )
RegisterEvent( "ACTIONBAR_PAGE_CHANGED", ReadKeybindings )
RegisterEvent( "ACTIONBAR_UPDATE_STATE", ReadKeybindings )
RegisterEvent( "SPELL_UPDATE_ICON", ReadKeybindings )
RegisterEvent( "SPELLS_CHANGED", ReadKeybindings )

(It's just adding the -- before the ACTIONBAR_SLOT_CHANGED line.)

Can you try that? Save the file and then /reload in game.

Yup, seems to be fixed ! Still having the stutter from changing talents but I guess it's normal because it has to calculate the new rotation.

Awesome :) Yeah so far I'm mostly using the shortcut to activate it on boss / deactivate it on packs and world content. I'm already tracking most of them, I just enjoy the no brain mode with Hekili when playing alts.

I also like the Bloodlust override feature, but sometimes it has to be delayed / it's off cd

Using this to ask a question, is there a way to show cooldowns separately from main bar ? For example to still have them displayed but not forcibly taking a spot in the rotation images ?

No, not at the moment.

Is it planned ?

Yes...ish.

I have a plan for a "tray" feature that basically does this, and can glow (or otherwise indicate) when the CD's criteria would be met. (If the icons are showing all the time, it's not really a "priority" any more and this addon is a priority helper.)

However, until that's ready, the smart/best option is to just get some WeakAuras for those key abilities that you want to be able to track all the time.

This is officially fixed in 1.0.14. Thanks!
