HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Question: Is it just me, or is this happening to others? 1, 2.

I noticed that the issue with the fifth slot disappearing started after it was added to the hero's equipment. The partial coloring of slots in the artifact merchant also wasn't present in version 1.0.

Something seems unclear about the slot. As for the artifacts in the second picture, there's a possibility that some application, like a player or one that uses transparency functions, is running in the background, even in a minimized state, and is causing issues due to insufficient memory for graphics processing.
