Is there a way to deactivate the hardware acceleration on OpenCV 3.0.0? I am getting the following errors on a Intel HD4000 Graphics core:

Unhandled exception at 0x0823E2E2 (igdbcl32.dll) in OpenCVFacade.exe: 0xC0000005: Access violation writing location 0x00000000.

This might be a issue with an old driver from 2012 which has to be updated by the company though. The cause is CascadeClassifier detectMultiScale.

Oh, and i do not use UMat.
