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?
