Wezterm Transparent/Acrylic Background Issue: Solution
Wezterm is a powerful, customizable, and feature-rich terminal emulator for Windows, macOS, and Linux. However, some users may face an issue with the background, specifically, with the transparent and acrylic backgrounds. This article will cover the problem in detail and offer a solution to help you effectively tackle this issue.
Understanding Wezterm Configuration
Wezterm's configuration is primarily managed through a Lua script. Users can create and modify their configurations according to their preferences. In the provided question, the installed Wezterm configuration looks like the following:
local wezterm = require("wezterm")
local mux = wezterm.mux
This basic structure initializes the Wezterm library and prepares it for the creation of a multiplexer (mux) object, which is used to manage windows and tabs in Wezterm.
The Problem: Transparent/Acrylic Background Issues
Some users may notice that the transparent or acrylic background does not work as expected in Wezterm. This issue can manifest in the following ways:
- The terminal background fails to display the correct level of transparency.
- The background does not blend well with the Windows desktop or other windows, creating a rough or jagged appearance.
- Transparent/Acrylic background is not applied consistently across all windows and tabs.
The Solution: Applying a Proper Transparency Setting
To resolve the transparent background issue in Wezterm, you need to apply specific transparency settings within the configuration as follows:
local wezterm = require("wezterm")
local mux = wezterm.mux
-- Set the appearance to enable acrylic background and set the opacity level
wezterm.set_config({
window_decorations = "RESIZE",
enable_acrylic = true,
acrylic_opacity = 0.75,
})
Explanation of the solution:
window_decorations: Set to "RESIZE" to configure window borders. This allows the terminal to have a consistent border, even when the background is transparent.enable_acrylic: Set totrueto use the acrylic background. This will enable a uniform, blended appearance on Windows systems.acrylic_opacity: Set to a value between0(completely transparent) and1(completely opaque). Fine-tune this value based on your preference.
