Blurred window

Introduction.
Zorro is a piece of software for developing & deploying automated trading
strategies.

Issue.
Once you minimize it's window and then maximize it back to normal size, the
window looks completely blurred.

How to reproduce this? 
Download Zorro from http://opserver.de/down/Zorro_setup.exe and run the default
installation.

Here's terminal output, note that the missing ForexConnect.dll library isn't
relevant to this problem.

//begin

wine zorro.exe
02d0:err:module:import_dll Library ForexConnect.dll (which is needed by
L"C:\Program Files\Zorro\Plugin\FXCM.dll") not found
02d0:fixme:imm:ImeSetActiveContext (0x2bff30, 1): stub
02d0:fixme:imm:ImmReleaseContext (000F040C, 002BFF30): stub
02d0:fixme:msvcrt:__clean_type_info_names_internal (003A73D4) stub
02d0:fixme:msvcrt:__clean_type_info_names_internal (026BE424) stub

//end

Attached you will find screenshot from Zorro after minimizing & maximizing it's
window.
