Mint Cinnamon: Cannot show minimized form

[CM630]

The following code shows a minimized form on Windows.
In Linux Mint Cinnamon it does on the second time - the event which executes the code needs to be fired manually twice before the form is shown, after the first execution nothing happens

Code: Pascal  [Select][+][-]

1.   self.WindowState := wsNormal;
2.   self.Show;

Also, the following code works from the first time:

Code: Pascal  [Select][+][-]

1.   self.WindowState := wsNormal;
2.   self.Show;
3.   ShowMessage ('');
4.   self.Show;

The following code improves nothing:

Code: Pascal  [Select][+][-]

1.   self.WindowState := wsNormal;
2.   self.Show;
3.   spleep(500);  
4.   self.Show;

Any idea how to fix this? I have not tried those (non)syncronous things, if no better solution exists, I will try them.

Hello.

Mint-Cinnamon uses Muffin window manager (a fork of Mutter WM).
And it has features "by design" that are indeed not fully compatible like other working WM.
(And Muffin devs do not have plan to fix it).

But the ShowMessage sort of solves the issue, so probably I can emulate a ShowMessage, which shows nothing?
I will try with a timer.

EDIT:
I made it work the following way:
 

Code: Pascal  [Select][+][-]

1. procedure TfrmMainForm.ShowApp;
2. begin
3.   self.WindowState := wsNormal;
4.   self.Show;
5.   self.BringToFront;
6.   self.SetFocus;
7.   {$IFDEF LINUX}
8.   tmrTray.Enabled := True;
9.   {$endif}
10. end;
11.  
12. procedure TfrmMainForm.tmrTrayTimer(Sender: TObject);
13. begin
14.   //Used only in Linux, to override a bug in Mint Cinnamon
15.   self.Show;
16.   tmrTray.Enabled := False;
17. end;
