Emulator

What's the problem?

1. Some texture in the menu z-depth not right, the text stand behind another texture so cannot be read.
2. Two texture group together, they have difference xy position. So, when one texture display right the other will goes wrong.

Dolphin version with the problem (as it appears in the title bar, Ex.: "R
4779" or "R 6403M"):
All revision.
(optional) Dolphin version that does not have the problem:

Was the ISO a plain dump from disc, compressed and/or scrubbed?

Please provide any additional information below.
I have do many test and here is the result.
The first picture show the screen after I try to fix the texture position. I hard code the viewport x and y value in the UpdateViewport() in Render.cpp so that now the red texture display correct but the blue one wrong. Then I find that red and blue texture are group together. When I move one, another will follow.
Also, the red texture (0,0) is in the center of the screen and the blue texture (0,0) is in the top-left corner.
Which means if I want one of it display in correct position, the other will display wrong.

Picture 2 is the screen that you will get if you don't do anything on a normal regular build. The blue one will display correct but the red one wrong.

Picture 3 show some texture z-depth is wrong so that the text stand behind another texture.

Sorry for my bad english...
