Application comes up black when using software sceneGraphBackend
-
I have a Qml application using QML with a c++ backend running under Qt 6.6 on AlmaLinux 9.1
I'm having some issues with the renderer.
When I set the software renderer...
QQuickWindow::setSceneGraphBackend("software");
my application often comes up as an all black window and stays that way until I mouse over it.
I switched from the default renderer to the software renderer for performance reasons. With the default renderer while running in a vnc session my application was generating a very heavy CPU load. I think this has something to do with the vnc session and the access it has to the graphics hardware.
I'm looking for any help either resolving the black screen with the software renderer or the performance issues of the default renderer.
Thanks.
