Inconsistent float side (icons jumping left and right on mouse move)

[Krutoy242]

When I move my mouse over the item, box with item display jumping from left to right.

• This happens only in specific inventory slots
• The X coordinate of "jumping" depends on window size

Do you have any other mods that affects gui scaling or tooltip rendering? I can't replicate this in my modpack.

That's the problem. My mod calculates tooltip positions with screen width from RenderTooltipEvent.Pre.getScreenWidth(), so gui scaling mods will break this.
I tweaked tooltip positioning behaviour in v1.6.3. This the compatibility with scaling mods isn't fixed, but the tooltip shouldn't jump to left-side now.
