Can't start onagre on arch linux, with a fresh install.

Describe the bug
A clear and concise description of what the bug is.

Just running onagre won't do anything. It shows a blank window with no options and won't accept text or respond to keyboard signals.

Running it with either the vulkan or gl backend, it briefly allows for some text and then hangs up again. Both backends do the same thing.

Running it with backtrace does nothing. Running with debug doesn't seem to reveal anything important. but I've included them here for posteritiy.

onagre_debug.log

Config
If relevant, provide a copy of your onagre config/theme.

Just using default nord theme. same thing happens with no theme.

To Reproduce

Also happens on my machine. Did a fresh debug build from latest git and ran with rust-gdb. The issue didn't manifestate when using Intel GPU but reliably happened on Nvidia GPU.

A similar hang in DispatchWaitForFences on Nvidia GPUs in other code is mentioned on an Ogre3d forum thread to which a buffer clear fix is suggested. Presumably the fix needs to be done in WGPU or Iced afaik.

[Jaakkonen]

In my case WGPU defaults to using Nvidia and Vulkan by default. Have you tried running it with WGPU_BACKEND=gl onagre? Or if you have an integrated graphics chip forcing Vulkan to use it instead of Nvidia graphics card?

[neevparikh]

It hangs with both gl and vulkan unfortunately :/ Best, Neev Parikh

Hey can you try with the latest version (cargo install --git https://github.com/onagre-launcher/onagre).
I think we are close to a stable release and I'd like to confirm this is fixed.

[markstos]

I just tried launching it with Arch Linux and Sway and it opened.
