Ui looks different in release mode

When I compile my project with Qt 5.10.1 in release mode, the UI looks different :

In debug mode :

In release mode :

Has anyone an idea of why it looks different when compiled in release mode ?

EDIT : I have this issue since I compile with Qt 5.10.1, it didn't occur with Qt 5.4.2

You need to give more information on OS and eventually compiler.

Do you have minimal compilable example for demostration?

I use Windows 7 and I have compiled it with MinGW 5.3 32 bits.

Well I cannot really share the code since it's a commercial application

You should try to replicate it with a minimal project created on your machine, which does show the same phenomen. Typically a short demo based on Qt creator templates would demostrate.

Otherwise I would expect that this is due to some macro switches within your code where the style is changed differently depending on macro setting for release and debug.

I don't have this issue with a minimal project, the QPushButton looks the same in both debug and release mode.
I have omitted to say that I used to compile my project with Qt 5.4.2 and didn't have the issue. It occured when I compiled it with Qt 5.10.1

Do you use stylesheets?

bam500

Yes I apply stylesheets to all my widgets

I have finally found the reason :

With Qt 5.10.1 you need to add the dll : plugins/styles/qwindowsvistastyle.dll at the root of your project.

Now it is working fine!

Here's where I got inspired : https://github.com/mxe/mxe/issues/2037 ;-)
