Resizing window does not work

[floriangriese]

I tried the example on http://www.glvisualize.com/examples/volumes/ and if I resize the window the rendering does not work anymore.

That's a linux driver bug :( I have a fix for that, which I deactivated because it worked fine for me lately. Maybe try updating the drivers!? I can also put back the (ugly) workaround...

Try replacing resize! in:
https://github.com/JuliaGL/GLWindow.jl/blob/v0.1.2/src/types.jl#L63
with :

function Base.resize!(fb::GLFramebuffer, window_size)
    ws = tuple(window_size...)
    if ws!=size(fb) && all(x->x>0, window_size)
        buffersize = tuple(window_size...)
        if OS_NAME == :Linux
            render_framebuffer = glGenFramebuffers()
            glBindFramebuffer(GL_FRAMEBUFFER, render_framebuffer)

            color_buffer    = Texture(RGBA{UFixed8},    buffersize, minfilter=:nearest, x_repeat=:clamp_to_edge)
            objectid_buffer = Texture(Vec{2, GLushort}, buffersize, minfilter=:nearest, x_repeat=:clamp_to_edge)
            depth_buffer    = Texture(Float32, buffersize,
                internalformat = GL_DEPTH_COMPONENT32F,
                format         = GL_DEPTH_COMPONENT,
                minfilter=:nearest, x_repeat=:clamp_to_edge
            )
            attach_framebuffer(color_buffer, GL_COLOR_ATTACHMENT0)
            attach_framebuffer(objectid_buffer, GL_COLOR_ATTACHMENT1)
            attach_framebuffer(depth_buffer, GL_DEPTH_ATTACHMENT)

            p  = postprocess(color_buffer, Signal(window_size))
            fb.id = render_framebuffer
            fb.color = color_buffer
            fb.objectid = objectid_buffer
            fb.depth = depth_buffer
            fb.postprocess = p
            glBindFramebuffer(GL_FRAMEBUFFER, 0)
        else
            resize_nocopy!(fb.color, buffersize)
            resize_nocopy!(fb.objectid, buffersize)
            resize_nocopy!(fb.depth, buffersize)
        end
    end
    nothing
end

thx I will first check the drivers!
