I run the example in the README and I get: http://storage3.static.itmages.com/i/17/0620/h_1497922783_2406791_1132230b22.png

@TomAshley303, judging from the screenshot, it's a mix of macos and linux environment? Could you please elaborate on your configuration? Can you please confirm that other SDL2 software works properly in your environment?

It's Kubuntu. 17.04 Just running the example from the readme. latest nim 0.17. idk about SDL2. I'm running KDE5/plasma.

This continues to happen. I'm on a different version of Linux now (KDE Neon) which is Ubuntu 16.04 with KDE 5.10.4. If I resize the window, it displays as normal until it loses focus in which case the focused window contents get frozen onto the nimx window. This is a fresh install. To get nimx to work, I installed the libsdl2-2.0-0 package and ran ln -s /usr/lib/x86_64-linux-gnu/libSDL2-2.0.so.0 /usr/lib/x86_64-linux-gnu/libSDL2.so.

using this code:

import nimx.window
import nimx.text_field
import nimx.system_logger # Required because of Nim bug (#4433)

proc startApp() =
    # First create a window. Window is the root of view hierarchy.
    var wnd = newWindow(newRect(40, 40, 800, 600))

    # Create a static text field and add it to view hierarchy
    let label = newLabel(newRect(20, 20, 150, 20))
    label.text = "Hello, world!"
    wnd.addSubview(label)

# Run the app
runApplication:
    startApp()

@TomAshley303 i've never seen such behavior with nimx, and have no idea how to fix it. I would suspect either hardware or specific software environment problem. So you're on your own here for now. As a start I would recommend you write a small sdl program in c and see how it works in your case.

I have a similar problem with example from readme. Just minimize and then maximize the window. image Asus laptop with Intel Core i3 4010U OS: Manjaro 17.0.2 Linux 4.12.3-1 DE: xfce4 4.12.4-1 Nim Compiler Version 0.17.1 (2017-07-25) [Linux: amd64] gcc 7.1.1 20170630

Tested in another environment. Cinnamon 3.4.3-1. Works without problems. Openbox 3.6.1-3. Same as in xfce4. But sometimes it crashes after maximization (Look at the terminal output) https://user-images.githubusercontent.com/25588359/28794755-d735a9e4-7650-11e7-9126-2389686489e8.png
