    Description

      Please run the attached example, the QSG_RENDERER_DEBUG=render shows, that the text is uploaded with every frame, which shouldn't be necessary.

      0x7fb62017d830 [  upload] [noclip] [ alpha] [  merged]  Nodes:    1  Vertices:    32  Indices:    48  root: 0x0 opacity: 1

      When the Text code is moved to the bottom or has a different z value than the particles:

      - 0x7fe50c1a2ce0 [retained] [noclip] [ alpha] [  merged]  Nodes:    1  Vertices:    32  Indices:    48  root: 0x0 opacity: 1

      no uploads are happening.
