Text: alpha blending of the fonts is not applied correctly in shader #1245
Description
The glyph texture uses the alpha channel to anti-alias fonts. This information is not correctly used in the text shader.
return vec4<f32>(color.rgb * c.a, color.a);
where c.a is the font texture.
this will make the color darker which will only work on a black background. Instead, the following should be used:
return vec4<f32>(color.rgb, c.a);
This will properly blend the font with the background. If the alpha channel in the color should be used to make transparent text, then
return vec4<f32>(color.rgb, color.a * c.a);
could be used.
