Qt Quick Images and Canvas are not correctly painted in release static build

Hi,

I have recently compiled Qt from the source (tag v5.12.5) on Windows using Microsoft Visual Studio 2019 Community. 

git clone git://code.qt.io/qt/qt5.git src
cd src
git checkout v5.12.5
perl init-repository -f --module-subset=qtbase,qtdeclarative,qtgraphicaleffects,qtimageformats,qtquickcontrols,qtquickcontrols2,qtwinextras,qtsvg,qtwebsockets,qtmultimedia
configure -confirm-license -recheck -prefix C:\Qt\5.12.5\msvc2017_64_static -commercial -debug-and-release -static -static-runtime -nomake examples -nomake tools -nomake tests -opengl dynamic -openssl-linked -I C:\vcpkg\installed\x64-windows-static\include -L C:\vcpkg\installed\x64-windows-static\lib OPENSSL_LIBS="libeay32.lib ssleay32.lib"

When building my application with this kit I have realised the existence of a bug that only seems to manifest when I choose to build the application in release mode. In debug mode, it draws correctly.

On my applications I make heavy use of images and canvas. Both are being affected.

I'm including a small examples that reproduces the problem. I also include two images, one from running in debug and the other one from running in release, to quickly illustrate the problem I'm experiencing.

Curiously, this bug doesn't manifest itself when using the kit provided by Qt 5.12.5 Maintenance Tool 

Thanks! 

Best regards
