## How to use it

### Window size

To access size settings, go to **Settings** > **Appearance** > **Window**.

* Enable "Open new windows with custom size", then configure your preferred columns and rows.

<div class="callout callout-note">

If [Session Restoration](https://funcoding.ai/agents/warp/terminal/sessions/session-restoration/) is enabled, Warp will restore the size of the last window closed when you quit the app. Either make sure the custom-sized window is the last one closed, or disable Session Restoration to ensure Warp launches with the custom-sized window.

</div>

### Window opacity

To access it, go to **Settings** > **Appearance** > **Window**

* The slider supports setting the opacity value between `1` and `100` where `100` is completely opaque or solid.

### Window blurring

After decreasing the opacity below `100`, you can blur the background or choose a Windows backdrop material.

* On macOS, use the blur slider. Increasing the slider increases the blur radius applied to the background image.
* On Windows, choose a **Window backdrop** material: **No material**, **Mica**, **Acrylic**, or **Mica Alt**. Backdrop is not visible at opacity 100%. In the settings file, this is `appearance.window.backdrop` (`none`, `mica`, `acrylic`, or `mica_alt`).

On macOS, large blur radiuses may affect performance, especially on Retina displays.

On Linux, window blurring is not supported.

On Windows, some graphics drivers may not support rendering transparent or translucent windows. See below for troubleshooting tips.

## How it works

### Troubleshooting transparency on Windows

<div class="callout callout-note">

At the moment, window opacity in Warp on Windows **does not work** in the following circumstances:

* When using DirectX 12 as the rendering backend
* When using any rendering backend with an Nvidia GPU when "Auto" or "Prefer layered" is selected as the value for "Vulkan/OpenGL present method" in NVIDIA Control Panel > Manage 3D Settings

</div>

Some graphics drivers and rendering backends may not support rendering transparent windows.

You can select the Vulkan or OpenGL graphics backend to render new Warp windows in the Settings menu, under **Features** > **System** > **Preferred graphics backend**.

You can also opt to render new Warp windows with an integrated GPU, under **Features** > **System** > **Prefer rendering new windows with integrated GPU (low power)**.
