Dear Author,
the specified functionality (Visual3d_Layer and Aspect_GraphicCallbackProc) is deprecated and will be removed in next release. Within current information it looks more like a bug in NVIDIA driver rather than in OCCT.
Please provide test scenario using actual API (AIS_TextLabel and Graphic3d_ZLayerId_TopOSD using Z-layers - but better by Draw Harness script) and actual version of OCCT (6.9.0) if the problem is still reproducible.
