If you update your Chakra GNU/linux system with appset or pacman after appset-tray-qt had changed to the arrow-icon that icon still stays without changing to neutral after the update was applied as it did before.
How to recreate:
Wait for a update
Update with pacman or appset
Tray still tells you about new updates and icon has arrow
Only changes to neutral after you checked for updates with appset-tray-qt
appset-tray-qt don't sync after update with database
