Label's text dipslay incompletely, or not correctly

[garric]

Hi,
I have met with a problem with Label's text display. It looks like if the text of Label 'prints' incompletely or not correctly(see sample text 'fdskla kls fsdfsdal' showed in the attachment)
I'm not sure whether if this problem is related to half-pixel, or with UV offset. I have ever tried to tweek position of label transform, and the frustrated thing is that,
1.text may display not correctly when world position of Label change
2.text display correctly at some screen resolution, but not for other screen resolution. (label piexle size are the same under all screen solution)
So, is there any suggestion or solution for this problem?
By the way, the font for Label is made within an sperate altas(only used for font) with 2048x2048 pixel size. And because we can drag the text, so the world postion of the text can change.

Check the font's atlas texture. Looks like you're using Point filtering. You need it to remain on Trilinear.

Text will get blurry as it moves because you're using such a thin font. You should use a thicker size font or make it bold.
