Small issue with Lazarus in that the app window in the created program seems to have a small white area at the top left just under the application icon.
It is not a component and the program is very basic so not sure what it is but would be nice to be able to remove it.

Anyone know how to fix.

Hi Jamie, Not sure how to upload image - Ok now i see it at the bottom for message windows.
Dooooh.

I've just tested on Windows 10, no problem as you can see on screenshot below.

You can try to run the code, here is the link:
https://forum.lazarus.freepascal.org/index.php/topic,74239.msg584799.html#msg584799

If the issue you mentioned does not happen on the code, that probably means there is a bug in your code.

If you need more codes to test, I would recommend you this link, which has many short demos:

Hi Jamie, Not sure how to upload image - Ok now i see it at the bottom for message windows.
Dooooh.

The title bar and border look so thick. It must be from OS styling.

It is not Windows. Which widgetset are you using? On Qt6 it also looks OK.

Ok tomorrow (late here in Oz) I will build very very basic app and see if it occurs. 
will let you know.

It is really difficult to guess without code, remember?
- platform
- widget set
- preferably code

Please....

I just mimicked Handoko's code with Qt6...

Ok built a small test program and I have found what I believe to be the culprit - Chilkat (Microsoft Graph library).
At the very top of the program I create a global variable to hold the licence for the DLL library with one line like this
    //oGlob := TaxcChilkatGlobal.Create(Self); 

When comment the line out - all is normal, when uncommented white block appears.
I image it is some sort of watermark of the license or some such and with Delphi it is possible hidden in the top bar but not with Lazarus.

Anyway I have written to Chilkat about a fix or work-around.

Ok the ChilKat support replied with the solution.

"The white marker is  the Lazarus ActiveX visual wrapper window being created for TaxcChilkatGlobal.
ChilkatGlobal is logically a non-visual COM/ActiveX object, but Lazarus imported it as a T... ActiveX control class.

When you do:
oGlob := TaxcChilkatGlobal.Create(Self);

Lazarus creates a small hosted ActiveX window/control on the form. That tiny white shape is the empty ActiveX host/control surface, not something drawn by Chilkat intentionally.
Use the non-visual COM object creation style instead of the T... wrapper, for example:"

Code: Pascal  [Select][+][-]

1. uses
2.   ComObj;
3.  
4. var
5.   glob: OleVariant;
6.  
7. begin
8.   glob := CreateOleObject('Chilkat.Global');
9.   glob.UnlockBundle('...');
10. end;

Sorry I should have added when implemented this fixed the issue - Happy now no more white square
