As far as I know UI Tetris developer took my code and did it's rewrite directly into his mod (with a permission) so ask him

Have made a post on his mod and linked to here. Made the report here as the error magnifier pointed to this mod. On the tetris mod page it says works great with htis mod, but you say he has incorporated it into his mod already?

did a little more testing, with this mod disable everything seems to function, but with this enabled, the second my mouse hovers over the players inventory UI, the mouse disappears, but once I move the mouse out of that inventory panel it comes back, and a few hundred errors appear, they seem to be stascking while the mouse is in the inventory panel, but they cant appear due to the UI being all bugged. Will try again with this and tetris but no spiffUI, as thats a possible culprit as it touches UI

I did not update this mod so it could be on Tetris UI side

I tested without spiffUI and the bug still happens with this and tetris. I will make a new thread over on tetris, with a link to this one, as to not bother you with the notification spam, my apologies, just figured it might be an issue over here as thats what error magnifier pointed to. Have a good day my man

It also might be load order. Try to load it before and after...

I just tried loading it before and after. same result unfortunately. It's almost like the player inventory window is being forced to render on top of everything else

Open inventory.
Drag the bottom of the inventory to make it smaller so it shows only a few items instead of the entire inventory.
Scroll past an item that has icon which the mod adds.
The icons from the item you scrolled past will appear clipping over the three sorting buttons above the item's icon.

Icons added by the mod should appear under not over those sorting buttons?

Used this method hook for better compatibility with some UI mods so yes

I mean over sorting buttons

So basically everything in inventory dialog renders and then KAC icons render above. So if any other UI mod use vanilla row heights (or changes it in ISInventoryPane.itemHgt) and uses same spacing from left then KAC icons render will be ok )
Recently I made KAC not local (private) anymore so now it's possible to make compatibility patches or even disable render I made and write a new render using my mod as API
