C++ Sample Window App that Flickers on Dock Restore

If you minimize the SDL application (Apple-M) and then restore the application by clicking it in the Mac Dock, you will see a window ficker before the restore occurs. I am including a sample application, just to make sure it isn't some setup issue I forgot to do.

I'm not seeing a flicker here on 10.8.  Jorgen, can you reproduce this?
Comment 2 Dan Unzen 2013-08-13 06:21:08 UTC 
It may be useful to include the entire Xcode project as the problem may be related to a project setting. Let me know if I should upload that as well.

XCode Project with included App that shows the problem

I have included the XCode project that shows the problem on my 10.7.5 Mac.

I see this issue on 10.9 as well. Sam, the thing is that you need to click the Dock icon for the app and *not* the dock icon for the minimized window.
Comment 5 Dan Unzen 2014-01-07 02:57:47 UTC 
On my Mac in System Preferences->Dock, I have "Minimize windows into application icon" selected. This may be why I was seeing this issue and others were not.
Comment 6 Dan Unzen 2014-01-07 02:59:54 UTC 
Also, I have upgraded to 10.9 as well and the problem still exists, as Jørgen already reported.
Comment 7 (disabled) Jørgen Tjernø 2014-02-26 19:47:21 UTC 
Assigning back to Sam, as I don't have time to look at this before 2.0.2.

Marking a large number of bugs with the "triage-2.0.4" keyword at once. Sorry if you got a lot of email from this. This is to help me sort through some bugs in regards to a 2.0.4 release. We may or may not fix this bug for 2.0.4, though!
Comment 9 Ryan C. Gordon 2015-04-08 01:24:38 UTC 
I think we fixed this at some point. At least, this used to be 100% reproducible for me and now it doesn't seem to happen.

Please reopen if you still see this behavior.
