Unsolved Crashing Application at Application Exit
-
Hello together,
I want to use a ConicalGradient int T.Button Element, because we need some special effetcts. So we overwrite the standard behaviour of the Button Element.
But the ConicalGradient Element in the T.Button Definitions seems to cause the crash at application exit.
I have no idea why is it so. Maybe someone has an Idea whats's going on.I have a minimal example uploaded to show the problem.

It seems that i don't have enough privileges to upload the example. Maybe my description is enough to understand the problem.

Just copy and paste the contents of the main .qml file. We don't need the C++ main() boilerplate. :)

Ok Here the Listing for the Button.qml i use:

Which Qt version and platform? It doesn't crash for me with Qt 5.10.1 on Linux or Windows. I tried with:
// main.qml import QtQuick 2.9 import QtQuick.Window 2.2 Window { visible: true width: 640 height: 480 Button { anchors.centerIn: parent } }and
Button.qmlwith the given content in the same folder. -
And the main.qml:
import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.3
import "myStyle"ApplicationWindow {
visible: true
width: 640
height: 480
title: qsTr("Hello World")Rectangle { Button { id: button1 x: 256 y: 86 text: qsTr("Press Me") } }}

Sorry, i forgot this information .
My Computer has Windows 10 installed.
We run the app under Msys64 with mingw32 started.
Qt has the version 5.9.2Greetings
