Empty or black window on Ubuntu 23.04

[XargonWan]

I tried to run it on Ubuntu 23.04 (Wayland) but I got a black squared window and this terminal output:

./clippy.desktop
[73922:0628/162948:ERROR:browser_main_loop.cc(170)] Running without the SUID sandbox! See https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment for more information on developing with the sandbox on.
Gtk-Message: 16:29:48.980: Failed to load module "canberra-gtk-module"
[73922:0628/162949:INFO:native_window_aura.cc(491)] if transparency does not work, try with --enable-transparent-visuals --disable-gpu
[73946:0628/162949:ERROR:sandbox_linux.cc(325)] InitializeSandbox() called with multiple threads in process gpu-process

If I run it with --enable-transparent-visuals --disable-gpu I got an empty transparent window and this output:

./clippy.desktop --enable-transparent-visuals

FYI: I had to install apt install libgconf-2-4.
