Application window resizes, crashes for multi-monitor Linux

[lbordowitz]

Description

(Potentially related to #149 )

Moving a window between monitors causes the window to resize uncontrollably large, and the application subsequently crashes:

An unexpected panic ocurred, the program has to exit.
Please report this error and attach the log file found in the directory of the executable.

The error ocurred in: /home/lbordowitz/.cargo/git/checkouts/azul-dependencies-70bb1f94316762f9/bf2933b/webrender-0.57.2/src/render_task.rs at line 46 in thread WRRenderBackend#0

Error information:
explicit panic

Version / OS

• azul version:
  master branch

• Operating system:
  Ubuntu

• Windowing system (X11 or Wayland, Linux only):
  X11

Steps to Reproduce

Create a new project, with main.rs as listed on Getting Started:

extern crate azul;

use azul::prelude::*;

struct MyDataModel { }

impl Layout for MyDataModel {
    fn layout(&self, _: LayoutInfo<Self>) -> Dom<Self> {
        Dom::div()
    }
}

fn main() {
    let mut app = App::new(MyDataModel { }, AppConfig::default()).unwrap();
    let window = app.create_window(WindowCreateOptions::default(), css::native()).unwrap();
    app.run(window).unwrap();
}

The Cargo.toml should have dependencies that look like this:

[dependencies]
azul = { git = "https://github.com/maps4print/azul" }

Thanks for reporting, but I don't think I can do much about this atm, way too busy.
