Hi, Sergey, some minor comments (may be unrelated to the fix):
1. LWComponentPeer.setVisible() can be made final. Do expect any subclass to override it instead of setVisibleImpl()?
2. invokeLater() in LWWindowPeer.setVisibleImpl(): I realize this is really painful issue, but I'd vote for removing this workaround. It would result in faster startup (although, the window will be solid gray for some time), and make LWAWT code similar to what we have on other platforms.
Then next step will to minimize the delay between showing the window and painting its content.
3. LWWindowPeer.replaceSurfaceData(): what are benefits of setBackground() + clearRect() over setColor() + fillRect()? Although we always expect the Graphics object to be Graphics2D instance, this unconditional cast doesn't look great.

Hi Everyone, Please review the fix. Notes from the bug and comments: 1. setVisible() should be called at the end of the peers initialization. We can move super.initialize() to the end of the peers initializations. Initialize() was split to initialize() and initializeImpl(). In the initialize() we call initializeImpl and then we call to setVisible(). initializeImpl overridden in subclasses. 2. Invokelater in the initialization/disposing is a tricky. Left it as is. Probably later it will be changed. Comments was updated. 3. replaceSurfacedata() should be moved outside of LWWindowPeer.setVisible() Done. Also duplicate code was extracted to setVisible() method which call setVisibleImpl(). 4. Backbuffer in replaceSurfacedata() should be initialized by clearRect instead of fillrect(composite is important). Done. related to composite. 5. During lwwindowpeer initialization we call two similar methods nativeSetNSWindowAlpha() and setAlphaValue(). nativeSetNSWindowAlpha() removed from CPlatformWindow.java.
