Hello!

I discovered that it's impossible to add empty lines in Label control
in Linux.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  
Label1.Caption:='one'+LineEnding               
 +'two'+LineEnding+LineEnding               
 +'three'+LineEnding+LineEnding+LineEnding                 +'four';  
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   object
Label1: TLabel    Left = 0    Height = 240    Top = 0    Width = 320 
 Align = alClient    AutoSize = False    Font.Height = 13   
ParentColor = False    ParentFont = False  end
Tested in Linux Mint 21.1 XFCE and 20.3 MATE. Lazarus version is
2.2.4.

For comparision in Windows it works as expected.

Any ideas? Thanks.

In Manjaro Linux it works with qt5 widgetset, but I can confirm the
issue when I switch to gtk2. As a workaround you could add a space:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm1.FormCreate(Sender: TObject);begin 
Label1.Caption:='one'+LineEnding                 +'two'+LineEnding+' '
+LineEnding                 +'three'+LineEnding+' ' +LineEnding+' '
+LineEnding                 +'four';end;
