Neither compositing nor TearFree directly affect the application's frame

As you can see, glxgears is running at thousands of frames per second,
sync-to-vblank is clearly not enabled.

Please provide the corresponding terminal output from running an affected
application with LIBGL_DEBUG=verbose vblank_mode=0 .
