qml6glsink: impossible to render in parallel into 2 (or more) qml6glsinks

Create a simple QML application with 2 (or more) qml6glsinks with 2 different pipelines (see attached files).

Observed behavior

The application crashes or shows only the stream attached to the first GstGLQt6VideoItem item from the .qml file (in the test application the snow pattern.

Expected behavior

Two streams shown independently (snow and smpte patterns).

Suggested correction

I found the correction (in my case) for this problem changing the code of the destructor of GstQSGTexture (gstqsg6material.cc file) from

delete m_texture;

to

m_texture->deleteLater();

Edit: merge request ready. I'll create a merge request soon.
