Intel
[ 08/12/2024 13:39:07.880 egl_init WARN ] The egl backend is still experimental, use with care.

Backend: egl

• Driver vendors:
• EGL: Mesa Project
• EGL driver: iris
• GL: Intel
• GL renderer: Mesa Intel(R) UHD Graphics (ICL GT1)

Backend: glx

• Driver vendors:
• GLX: Mesa Project and SGI
• GL: Intel
• GL renderer: Mesa Intel(R) UHD Graphics (ICL GT1)
• Accelerated: 1

Configuration:

Configuration file

// Paste your configuration here
backend = "glx"
corner-radius = 20

rules: ({
  match = "focused";
  shader = "/home/kz87/Code/picom-shaders/default.glsl";
  corner-radius = 1;
})

Steps of reproduction

1. Make .glsl file with the following code:

#version 330
in vec2 texcoord;             // texture coordinate of the fragment

uniform sampler2D tex;        // texture of the window

// Default window post-processing:
// 1) invert color
// 2) opacity / transparency
// 3) max-brightness clamping
// 4) rounded corners
vec4 default_post_processing(vec4 c);

// Default window shader:
// 1) fetch the specified pixel
// 2) apply default post-processing
vec4 window_shader() {
    vec2 texsize = textureSize(tex, 0);
    vec4 c = texture2D(tex, texcoord / texsize, 0);
    c = default_post_processing(c);
    c.xyz *= 0;
    return c;
}

2. Run picom and specify shader path through the config file provided above

Expected behavior

Almost all windows should have corner-radius of 20 and no shader, except the focused one, which should have corner-radius of 1 and be completely black

Current Behavior

The corner-radius of the focused window does change, but the shader isn't applied

Sorry, closed the wrong issue

Not just shader in the new rules... It was broken everywhere actually. Should be fixed now.
