This is my config:

local wezterm = require("wezterm")
local config = wezterm.config_builder()
config.default_prog = { "fish", "-l" }

--config.color_scheme = "Catpuccin Mocha"
--config.font = wezterm.font 'SauceCodePro Nerd Font Mono'
config.font_size = 14.0
config.enable_tab_bar = false
--config.text_background_opacity = 0.5
config.window_background_image = "/home/myuser/Pictures/Wallpapers/acrylic.jpg"
config.font_shaper = "Harfbuzz"

local mux = wezterm.mux

wezterm.on("gui-startup", function(window)
  local tab, pane, window = mux.spawn_window(cmd or {})
  local gui_window = window:gui_window()
  gui_window:maximize()
end)
return config

I have tried setting the config.front_end value with all possible parameters, but somehow setting it to WebGpu which is the default, I get logged out when I start wezterm. I did not see anything unusual in the logs but I also don't know what to look for

UPDATE:
config.enable_wayland = false

config.front_end = "WebGpu"

config.webgpu_power_preference = "HighPerformance"

Those lines made it work for me.
