Re: wxPython Phoenix fails to LoadPerspective on Linux

I've been trying different combinations, and it looks to me that the issue 
is in the _mgr.Update() method.
Even getting rid of perspectives and directly showing/hiding the pane 
doesn't solve the problem:

import wx
import wx.lib.agw.aui as aui


class MyFrame(wx.Frame):

    def __init__(self, parent, id, title):

        wx.Frame.__init__(self, parent, id, title)
        self._mgr = aui.AuiManager()
        self._mgr.SetManagedWindow(self)

        # Create panels
        self.panel0 = MySidePanel(self)
        self._mgr.AddPane(self.panel0,
                          aui.AuiPaneInfo().
                          Name("Panel0").
                          Left())

        self.panel1 = MyDummyPanel(self)
        self._mgr.AddPane(self.panel1,
                          aui.AuiPaneInfo().
                          Name("Panel1").
                          CenterPane())

        # start with side panel only
        self._mgr.GetPane("Panel1").Hide()
        self._mgr.Update()


class MySidePanel(wx.Panel):

    def __init__(self, parent):
        self.frame = parent
        wx.Panel.__init__(self, parent, -1)

        self.button = wx.ToggleButton(self, label="Show")
        self.button.Bind(wx.EVT_TOGGLEBUTTON, self.on_button)
        self.Fit()

    def on_button(self, event):
        if self.button.GetValue():
            self.frame._mgr.GetPane("Panel1").Show()
            self.frame._mgr.Update()
            self.button.SetLabel("Hide")
        else:
            self.frame._mgr.GetPane("Panel1").Hide()
            self.frame._mgr.Update()
            self.button.SetLabel("Show")


class MyDummyPanel(wx.Panel):

    def __init__(self, parent):
        wx.Panel.__init__(self, parent, -1)
        wx.StaticText(self, -1, "foo foo foo")
        self.Fit()


app = wx.App(False)
frame = MyFrame(None, wx.ID_ANY, "Aui Manager Test")
frame.Show(True)
app.MainLoop()

It's as if the Update call didn't actually draw the new layout on Linux.

I know, but I need to use it with Python 3, so using wx 3.0.2 (classic) is 
not an option.
