Drawing on top of wx.Bitmap which contains alpha channel is different on Windows and Linux

Please create a ticket for this at trac.wxwidgets.org. Keep in mind that the person who works on this will probably be a C++ developer so try to be detailed enough about what you are doing and what is not working when you write the description that they will be able to reproduce the problem without Python.

Trying to load PNG image file which contains alpha channel to
StaticBitmap widget and draw circle on top of it.
This code works properly on Windows and doesn't - on Ubuntu 12.04.
On Ubuntu alpha channel is lost when bitmap is selected by DC.
*img.png* - PNG with alpha channel
*bitmap_in_make_func.png* is same as *img.png* - both contain alpha channels

How to fix this issue?
