Describe the Bug/Issue
Ive frequently noticed that with frost mage since I started on the spec yesterday. That the spells in the queue will quite often very rapidly flicker between the choices when casting flurry with the brain freeze proc, and ice lance is showing as recommended.
Its not pleasant for my eyes to look at for long. I wanted to hear if that is intended behavior.
But should I hazard a guess, its because flurry is a multihit spell, combined with it adding winters chill that will empower ice lance that causes the issue.. Though there seem to be a spell interaction that I cant precisely pin down since it doesnt happen all the time.

Describe the Bug/Issue
Rapid flickering of Ice Lance icons in queue list after casting Flurry when Fingers of Frost is NOT present and Icicles is at 5, and then casting Flurry once Brain Freeze have procced
If Fingers of Frost is present, the issue does not happen.

To Reproduce
Cast Frostbolt till till Icicles is at 5 stack, which will trigger Ice Lance recommendation. Continue casting Frostbolt till Brain Freeze have procced and giving you an instant cast Flurry that will apply Winter's Chill. If Fingers of Frost have procced as well, click away the buff to just have Ice Lance recommended from 5 stack Icicles alone - you may have to cast Frozen Orb/Icy Veins to ensure both are on cooldown to not intrude on the queue, then cast Flurry and the flickering will happen. I speculate its related to each impact of Flurry.

Expected behavior
No icon flickering.

PUT ERROR MESSAGE(S) HERE:

Its casting Flurry with Brain Freeze, while Fingers of Frost is NOT present. And that Icicles is at 5 stacks.

I am not certain whats missing from here.

Frost mage snapshot:

Frost mage here as well, using v9.0.5-1.0.1a and glacial fragments legendary (now named Icebringer, if that matters at all).
I was getting spam errors before the bandaid but still getting them after updating.

Weird thing is the snapshot spam stops and everything goes back to normal if I unequip the Icebringer legendary (I picked pants slot) and starts again if I put them on.

I could use more information about what it flickers between -- i.e., if it's flickering, I really need a snapshot of the two scenarios it flickers between. Then I can investigate whether there's an aura detection issue, a spell impact timing issue, or if it really is just a really narrow window between the two recommendations.

After2.txt
Before.txt
After.txt
I think After2 may be the better one, as that is right after the flickering stopped on a new round. After was mid-flickering.

Ok, as far as reproducing it reliably, its under these conditions:
Both Icy Veins and Frozen Orb is on cooldown, so the bar recommendation looks like 2x Ice Lance and 1x Flurry.
The issue does not happen if Frozen Orb and Icy Veins is present on the recommendation bar.
Buffwise, Fingers of Frost is NOT present, but Brain Freeze is present.
Then an Ice Lance icon will rapidly flicker between Frostbolt and Ice Lance, x3 times, upon casting Flurry. And Flurry makes x3 impacts.

The piece you seem concerned about is likely a function of travel times for spells. I don't have a solution for this, and it's been hard for me to track your explanation. I'm going to close this ticket.
