# Size, Opacity, & Blurring

Configure window size, opacity, and background blurring to match your visual preferences.

## 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.

Note

If [Session Restoration](/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.

### 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 Opacity (moving the slider to a value less than `100`), you can also blur the background.

-   On macOS, this is done using the blur slider. Increasing the slider increases the blur radius that’s applied to the background image.
-   On Windows, this is done by toggling the Acrylic background texture on or off.

Caution

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

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

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)**.
