Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

I don't trust developers (including myself), so on my personal PC I do programming inside a VM. As a benefit, I get a clean system without tons of library pollution, as a drawback, things sometimes just don't work, the same happens to iced inside a vagrant box with GUI forwarded through ssh. The window appears, but the whole canvas is just white.

Unfortunately, I can't provide viable steps, I tried to make them up, but probably I need to install more libraries or something, cuz now it's even worse, the screen is black and the app terminates immediately with a message Segmentation fault (core dumped).

Steps to (try to) reproduce:

1. Create a box

vagrant init ubuntu/focal64

2. Enable X forwarding

vim Vagrantfile

Add these lines before the last end:

config.ssh.forward_agent = true
config.ssh.forward_x11 = true

You can also optionally uncomment the config.vm.provider "virtualbox" do |vb| and ask for more CPU and memory to make compilation faster

vb.memory = "6144"
vb.cpus = "12"

3. Start the VM

vagrant up
vagrant ssh

4. Inside the VM, install necessary software and run the example

sudo apt update && sudo apt upgrade && sudo apt install -y build-essential x11-apps mesa-utils libxrandr2 libxi6
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

1<Enter>

source $HOME/.cargo/env
git clone --depth 1 https://github.com/iced-rs/iced.git
cd iced/
cargo run --package clock

5. Observe the white screen and these errors in the logs (or the seg fault)

libEGL warning: DRI3: failed to query the version
