I built opencv 2.4.10 from source in ubuntu 16.04.
I am getting this message `init done opengl support available`
I am trying to run the `grabcut.py` example provided by opencv , but whenever I right click I get a dropdown and options like
Panning left
Panning right
Panning up
Panning down etc
After I grab certain part of image , and start foreground extraction process the grabbed part of the image changes on it's own.
I tried the solutions on SO and here.
I deleted the contents of `window_QT.cpp` as suggested in the comment [here](http://answers.opencv.org/question/91423/supressing-init-done-and-opengl-support-available/).
I rebuilt the library as suggested [here](http://stackoverflow.com/a/31154073/5465739).
CMAKE -
`cmake -Wno-dev -G "Unix Makefiles" -D CMAKE_CXX_COMPILER=/usr/bin/g++ CMAKE_C_COMPILER=/usr/bin/gcc -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=OFF -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=OFF -D WITH_OPENGL=OFF -D BUILD_FAT_JAVA_LIB=ON -D INSTALL_TO_MANGLED_PATHS=ON -D INSTALL_CREATE_DISTRIB=ON -D INSTALL_TESTS=ON -D ENABLE_FAST_MATH=ON -D WITH_IMAGEIO=ON -D BUILD_SHARED_LIBS=OFF -D WITH_GSTREAMER=ON -D OPENCV_ENABLE_NONFREE=ON -D WITH_OPENCL=OFF ..`
What might be the issue?
I recently removed previous install of ubuntu to build it from source to include the non-free modules. Is it possible that the previous install might not have been remove cleanly and thus causing this error.
