Galactic Civilizations III\data\Core\UISizeDefs.xml
<UISize>

<Size>Small</Size>
<Multiplier>1.00</Multiplier>
<MinimumDisplayWidth>1024</MinimumDisplayWidth>
<MinimumDisplayHeight>768</MinimumDisplayHeight>
</UISize>

If you lower the multiplier below 1.00 (even 0.99) you get a weird blue shader box. I can edit the Font Size but I cannot find where you edit the size or location of the shader box.

I'm trying to make the game scale to 1336 x 768 but need help finding the location of these blue boxes.



I'm pretty sure its:

Galactic Civilizations III\data\Core\GraphicAssets.xml

<Asset>
<Tag>COMPUTE_SHADER_FILE_HORZ_BLUR</Tag>
<Filename>gfx\shaders\HorzBlur4.cso</Filename>
</Asset>

<Asset>
<Tag>COMPUTE_SHADER_FILE_VERT_BLUR</Tag>
<Filename>gfx\shaders\VertBlur4.cso</Filename>

How can I edit this? 

At 99% it appears.
