glxgears shows 60 fps (using binary nvidia driver). just to be complete: i had a linker error first when building gnuradio using pybombs, which i didn't yet mention. The output is shown below. It seemed not critical to me since it happens when linking an example. I 'solved' it by commenting the "add_subdirectory(examples/c++)" in gr-uhd/CMakeLists.txt . Maybe i made a wrong assumption and could this be causing the problem mentioned before? Or maybe this error can be helpfull for diagnosing the issue?
