Description
When using QBackingStore to render raster in QWindow on Linux it is enough to add to constructor of child class of QWindow (as described in docs https://doc.qt.io/qt-5/qwindow.html#setFormat) :
{
...
QSurfaceFormat fmt = format();
fmt.setAlphaBufferSize(8);
setFormat(fmt);
create();
...
//new QBackingStore(this)
}
and background becomes transparent.
On MacOS with the same code it is filled with gray color.
