Blur [#blur]

Blur creates a frosted glass effect for transparent windows.

| Setting                  | Default | Description                                                                                                                                                                                    |
| :----------------------- | :------ | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `blur`                   | `0`     | Enable blur for windows.                                                                                                                                                                       |
| `blur_layer`             | `0`     | Enable blur for layer surfaces (like bars/docks).                                                                                                                                              |
| `blur_optimized`         | `1`     | Caches the wallpaper and blur background, significantly reducing GPU usage. Disabling it will significantly increase GPU consumption and may cause rendering lag. **Highly recommended.** |
| `blur_params_radius`     | `5`     | The strength (radius) of the blur.                                                                                                                                                             |
| `blur_params_num_passes` | `1`     | Number of passes. Higher = smoother but more expensive.                                                                                                                                        |
| `blur_params_noise`      | `0.02`  | Blur noise level.                                                                                                                                                                              |
| `blur_params_brightness` | `0.9`   | Blur brightness adjustment.                                                                                                                                                                    |
| `blur_params_contrast`   | `0.9`   | Blur contrast adjustment.                                                                                                                                                                      |
| `blur_params_saturation` | `1.2`   | Blur saturation adjustment.                                                                                                                                                                    |

> **Warning:** Blur has a relatively high impact on performance. If your hardware is limited, it is not recommended to enable it. If you experience lag with blur on, ensure `blur_optimized=1` — disabling it will significantly increase GPU consumption and may cause rendering lag. To disable blur entirely, set `blur=0`.

Shadows [#shadows]

Drop shadows help distinguish floating windows from the background.

| Setting                | Default      | Description                                                 |

Opacity & Corner Radius [#opacity--corner-radius]

Control the transparency and roundness of your windows.
