Will do. I've not noticed any recently, used to bug instances where I found it back in Legacy.
For those unaware of what z-fighting (also called stitching) is:
I ran across it more on indoor maps than outside.
I have often wished both during Legacy and now that there was a Random character generation button for Origin/Arch/Powersets, not just the costume creator. For the times when I just couldn't decide.
Perhaps provide your settings/scaling info/system info. That may provide further clues to the devs on where the issue lies with regards to clickable areas not aligning with their respective buttons.
This is on a new character I take it? Can you provide a screenshot of the character? I know some costume pieces have restrictions, but I've not seen an issue with being unable to change skin colour.
You might also try in Discord.
There's the #supergroup-looking channel and each server has a 'recruit' channel for people searching out SG's.
Our own SG members do not balk at players using KB, especially since one plays a Kheld often, but it's just a handful of us who also used to play together on Legacy so we don't actively recruit.
