Hello. I have the same problem and it may be caused by focus being stealed by tooltips. Adding rule

{ rule = { },
  propertities = {
  focus = false  
} },

may help. I don't know how to limit the range of rule to tooltip so I have to set focus to false globally. There may be a better solution.

Thanks Han. Focus seems to be the problem. However, I put the following code in my rc.lua to fix it without loosing the ability to loose focus on other windows.

_old_filter = awful.client.focus.filter
awful.client.focus.filter = function(c)

    if c.type == 'dialog' and string.match(c.class, 'MATLAB') then
      return nil
    end

    return _old_filter(c)

end

An elegant solution using an awesome wm rule:

{ rule = { class = "MATLAB", type = "dialog" },
    properties = { focus = false }
},

It looks like Arch Linux is not officially supported by MathWorks. Hence the behavior might not be tested on it. Below link specifies the supported Linux versions for R2015b:

Have you observed this behavior in one of the supported Linux distributions?

Thanks for the reply. No, I've not tested it on any of the supported distributions. Do you think my window manager could cause this issue (I do not have any composting enabled)?
