QOpenGLTexture cannot destroy() texture on sharedcontext

"To set up sharing between QOpenGLWidget instances belonging to different windows, set the Qt::AA_ShareOpenGLContexts application attribute before instantiating QApplication. This will trigger sharing between all QOpenGLWidget instances without any further steps."

I set QCoreApplication::setAttribute(Qt::AA_ShareOpenGLContexts); I can draw the texture on any window, yet I can't call destroy() on a qopengltexture without error.

Requires a valid current OpenGL context.
Texture has not been destroyed
