Blurry UI

[scifi6546]

I am building an integeration for egui in my custom engine and I can not get the blurry windows to go away. I think I am using the same colorspace as in the web integeration.
here are my shaders. The one thing I am not doing is using the scissors but that should not effect the blurriness that I am seeing.
vertex shader.

in vec3 position;
        in vec2 uv;
        in vec4 vertex_color;
        out vec2 o_uv;
        out vec4 o_color;
        uniform mat4 camera;
        uniform mat4 model;
        vec3 linear_from_srgb(vec3 srgb) {
            bvec3 cutoff = lessThan(srgb, vec3(10.31475));
            vec3 lower = srgb / vec3(3294.6);
            vec3 higher = pow((srgb + vec3(14.025)) / vec3(269.025), vec3(2.4));
            return mix(higher, lower, vec3(cutoff));
        }
        // 0-1 linear  from  0-255 sRGBA
        vec4 linear_from_srgba(vec4 srgba) {
            return vec4(linear_from_srgb(srgba.rgb), srgba.a / 255.0);
        }

        void main() {
            gl_Position = vec4(position,1.0);
            o_uv = uv;
            o_color=linear_from_srgba(vertex_color);
        }

Fragment Shader

        fragment_shader: r#"#version 300 es
        precision mediump float;
        
        out vec4 color;
        in vec2 o_uv;
        in vec4 o_color;
        uniform sampler2D u_texture;
        
        vec4 onify(vec4 v){
            return v*vec4(0.001,0.0,0.0,0.0)+vec4(1.0,1.0,1.0,1.0);
        }
        vec4 one_alpha(vec4 v){
            v.w=1.0;
            return v;
        }
        // 0-255 sRGB  from  0-1 linear
        vec3 srgb_from_linear(vec3 rgb) {
            bvec3 cutoff = lessThan(rgb, vec3(0.0031308));
            vec3 lower = rgb * vec3(3294.6);
            vec3 higher = vec3(269.025) * pow(rgb, vec3(1.0 / 2.4)) - vec3(14.025);
            return mix(higher, lower, vec3(cutoff));
        }

        // 0-255 sRGBA  from  0-1 linear
        vec4 srgba_from_linear(vec4 rgba) {
          return vec4(srgb_from_linear(rgba.rgb), 255.0 * rgba.a);
        }
        vec3 linear_from_srgb(vec3 srgb) {
            bvec3 cutoff = lessThan(srgb, vec3(10.31475));
            vec3 lower = srgb / vec3(3294.6);
            vec3 higher = pow((srgb + vec3(14.025)) / vec3(269.025), vec3(2.4));
            return mix(higher, lower, vec3(cutoff));
        }
        // 0-1 linear  from  0-255 sRGBA
        vec4 linear_from_srgba(vec4 srgba) {
            return vec4(linear_from_srgb(srgba.rgb), srgba.a / 255.0);
        }

        void main() {
            color = srgba_from_linear(o_color*texture(u_texture,o_uv))/255.0;
            color.a = pow(color.a,1.6);
        }

Thanks for any help

Have you set the correct pixels_per_point in RawInput (https://docs.rs/egui/0.10.0/egui/struct.RawInput.html#structfield.pixels_per_point) ?

Also: have you read https://github.com/emilk/egui#debugging-your-integration ? :)

I have read the help guide. My rendering engine works with egui in version 0.6. I am going to try to incrementally increasing the version number. I updated pixels_per_point and nothing really changed.

confirmed that the bug happens between 0.7 and o.8
