win32_system_backdrop = SETTING¶
Since: Nightly Builds Only
The functionality described in this section requires a nightly build of wezterm. You can obtain a nightly build by following the instructions from the Download section.
When combined with
window_background_opacity, chooses from available
window background effects provided by Windows.
The possible values for
"Auto"- the system chooses. In practice, this is the same as
"Disable". This is the default value.
"Disable"- disable backdrop effects.
"Acrylic"- enable the Acrylic blur-behind-window effect. Available on Windows 10 and 11.
"Mica"- enable the Mica effect, available on Windows 11 build 22621 and later.
"Tabbed"- enable the Tabbed effect, available on Windows 11 build 22621 and later.
On Windows systems earlier than build 22621, the Acrylic affect can be adjusted using win32_acrylic_accent_color. More recent versions of Windows do not permit configuring the accent color for Acrylic, so that option has no effect there.
The Acrylic setting uses more resources than the others.
You need to reduce the
window_background_opacity to a value lower than
for the backdrop effect to work. For best results with both
window_background_opacity = 0 is recommended.
See also macos_window_background_blur for a similar effect on macOS.
