Hi, just registered to add to this observation. I've been fighting with this rather annoying issue for a long time now, even with the Windows 11 and the latest HWiNFO beta. It seems that when the tray icons have similar labels (tooltips), for ex. "Drive Temperature" and "Drive Temperature 2", no matter what, one of these will not stick, and will hide under the arrow. This is solved by completely renaming one of the icons in the HWiNFO sensor settings.
