There seems to be something wrong with the mana requirement display for mana pool infusions in NEI.
The most obvious thing is that the display is wrong by a factor of ten. Going by the numbers used with modtweaker (and testing the actual infusion), a full mana pool equates 1.000.000 units. The bar on NEI is full at 100.000 units. Going above that results in render bugs, for example with 500.000 units I have a second full bar rendered in the middle of the NEI item display on the right side of my screen.

A second related or unrelated issue is when I set mana requirement to 12.500 units. That should (currently) display as 1/8th of a full pool but looks significantly less, I'd say about like 5% of a full pool. 25.000 units displays "correctly" as 1/4th of a full pool.

Finally, to prevent confusion with how I titled the issue, it is not a new one, I just confirmed it in the current version.

Thanks =)

That is intended. If it was at a 1:1 scale it would render at 1px for most items, making it so you really couldn't tell the difference.

Would it be at least possible to get rid of the render bugs when using large requirements? So rendering caps out at 100.000?

Sure, that's doable.
