No, and I'll explain why below

Describe the bug

On starting wezterm I get ERROR wezterm_gui::frontend > Failed to create window: failed to get font metrics!?: FcResultNoMatch

I've only tried the version in your first build instructions, will try the nightly later.

I am trying to run WezTerm in a Docker image from https://github.com/jlesage/docker-baseimage-gui Yes I know this is an odd setup. I suspect I'm missing fonts or some other dependency but I thought the error message was obscure enough to report.

This image is based on Alpine 3.18 and I have installed the following dependencies: libgcc libxkbcommon xcb-util-image xcb-util libxcb libxkbcommon-x11 libx11 fontconfig wayland-libs-egl wayland-libs-client

To Reproduce

FROM alpine:3.18 as builder
RUN apk update && apk add curl

RUN curl -LO https://github.com/wez/wezterm/releases/download/20230712-072601-f4abf8fd/wezterm-20230712-072601-f4abf8fd-src.tar.gz
RUN tar -xzf wezterm-20230712-072601-f4abf8fd-src.tar.gz
RUN cd wezterm-20230712-072601-f4abf8fd && ./get-deps && cargo build --release

FROM jlesage/baseimage-gui:alpine-3.18-v4

RUN add-pkg libgcc libxkbcommon xcb-util-image xcb-util libxcb libxkbcommon-x11 libx11 fontconfig wayland-libs-egl wayland-libs-client

# Copy the start script.
COPY startapp.sh /startapp.sh

ENV HOME=/config
COPY --from=builder /wezterm-20230712-072601-f4abf8fd/target/release/wezterm /usr/bin/wezterm
COPY --from=builder /wezterm-20230712-072601-f4abf8fd/target/release/wezterm-gui /usr/bin/wezterm-gui

startapp.sh is just exec /usr/bin/wezterm

Configuration

no config

Expected Behavior

wezterm runs... slowly.

Sounds like a font problem in that environment. See: https://wezfurlong.org/wezterm/troubleshooting.html#debugging-font-display
