GDI+ & LAYERED Window == No Live Preview?

[Taz77]

Hi, since days I have a problem which I get not solved.
The problem is that the content of the second GUI does not show in the Live Preview, when the window is minimized.

(The second GUI is, required to get the transparency for the GUI)

 

That is the example GUI:

 

So it looks right:

 

But when the GUI is minimized, looks like this:

 

Source Code:

#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
#include <GDIPlus.au3>

I hope you can help me

PS: Sorry my English is not really good

Did you ever figure this out? I have a similar issue. Noticed it only occurs when using a basic theme in Windows 7 but works fine when using one of the Aero themes.

No, no solution is found

[Taz77]

The problem still exists, can anyone help?

Why do you think that this preview issue is related to AutoIt?

[Taz77]

I think so, it works on your PC? I have test it on windows 7 64 bit.

[UEZ]

Not working on Win8 / Win10.

 

Why don't you draw the text onto the bitmap and display only one GUI?

Because it is complex GUI, with many labels, buttons, lists...
And i want to make a template, so I can use Koda, to create easy guis, with this style.
