Double Input Bug?

I've been having an issue with inputs doubling. At first I thought it was something on my PC but now I'm thinking it's related to network latency or some sort of predictive networking.

Fairly frequently, I'll have attacks double, I disabled everything that interacted with my mouse but my keyboard skills would do it too. I've found I can replicate this very reliably with the following.

In hideout (using Shrine in this case, not sure it matters), map portals open (also not sure it matters), then open Stash with left click and immediately click off of it with an attack skill (I've tested this with both mouse bound and keyboard bound, it works with them all).

This may be an issue with my network provider as well, Starlink. I'm thinking there may be some repeats going through due to packet loss, which is inherent with any satellite internet. If I check the stats, it shows a Ping success of 99.91%. So it's dropping something somewhere. Latency is always around 40-70ms though.

Not really sure this constitutes a bug, but I figure if anyone else has Starlink and is facing these issues, they might find this useful.

*Edit*

I switched back to a land connection, we're switching network providers so it makes it easy to test both. Turns out I can replicate this with a DSL connection though it's a little harder. I found if I first have Guild Stash open, click on my Stash, and immediately click off with an attack skill, I can get a double input attack. So if it's not Starlink, then not sure what's causing it. It does happen in dungeons fighting mobs, which can be problematic for hit and run characters.

I'm on pc as well, with gamepad ( gamesir g7 se ) i'm always checking network latency but there is no spike and sometimes i also get double input with skills , currently experiencing double cast of shockwave totem , mostly after dodge rolling . Gamepad is new , just got it for poe 2 , there is also a bug that disables using skills when dodge rolling near an interactable item ( door , chest , loot etc.)

I have been getting this double input bug with the same controller as you, wired connection. I can easily replicate it, I just have to play the game and every 3 or so attacks with spiral volley it casts 2. This is close to build-breaking as it has a pretty high chance to lose all frenzy charges for nothing.

A friend is also getting double inputs of his comet which is actually killing him as he is carefully spending health to cast spells. He is using a xbox one controller wired.

I am going to try to lower polling rate from 500hz to 250hz and test after .
I am randomly getting double inputs while moving/dodging/targeting and casting ,
Sometimes i even hear the flasks getting used twice like bubble bubble sound effect .
This is only on poe 2 , i have tested on multiple other games , including arpgs ( chronicon , grim dawn, d2r ) the new khazan first berserker demo ( like black myth wukong /nioh ) and fighting games where you can see the command input history of the buttons in practice mode ( soul calibur 6 mainly ) and did not have any problems there .

EDIT : I tried the focus fire setting , as i had a feeling it had to do with the targeting of mobs , since i toggled focus fire and kept my right thumb OFF the right stick ( to not interfere with the targeting ) i have not been getting double inputs at all . so definitely it is something tied to the targeting system . Please check !

It does appear to be linked to the targeting system in some way as that is where this happens for me the most. I am on PC with WASD movement using left-click to fire my crossbow. It occasionally fires twice, accounting for attack speed, and when it does so it always repeats the target of the first attack. Sometimes that is a spot on the ground, but usually it is an enemy even if that enemy died to the first shot.
As I am constantly moving with WASD, when the crossbow repeats its attack targeting the last location it comes from my current location often meaning it is going there from a different angle and I am shooting in the wrong direction which can be very frustrating when surrounded. I notice that the higher my click rate, the more it tends to happen. There are even quite a few cases where I attack with the last of my ammo, reload, and then it still attacks/repeats target on the old location. Internet stability/ping does not seem to be a factor in the for me.

I have been trying to track down another bug that I keep experiencing, but as I keep trying and testing and playing I think I actually believe it to be the same bug as here, or at least related.
Occasionally when attempting to switch bolt types in my crossbow it just, doesn't. I get stuck with the same type somehow even though I hear it play the click/load sound. As I paid attention and tried to replicate it, I noticed that it only occurs when the system is trying to "Double shoot" appearing to process this doubled input instead of my input to switch skills. This means that my next intentional shot is not with the skill I want which more often than not leads to me being very dead.

I tested gamepad on multiple games , changed polling rate 250-1000hz , no problem there, so the issue is with poe 2 .

I have then played through steam to change controller settings/type through steam settings but still the same - tested essence drain and xbow/grenades with default targeting , the double cast persists, focus fire targeting no issue but with focus fire it's a hassle to target interactable objects while in-fight with the right stick like opening chests/looting .

So definitely an issue with the targeting system when using controller
( at least on PC , don't have console to check, i would've if i did ) .
