Segmentation fault with connection through ssh X forwarding

I have CodeXL installed on an Ubuntu box with Kaveri processor. I realized that remote connections work from some machines and it does not work from some. I have one machine with AMD GPU that CodeXL works. But 2 machines with Nvidia GPUs which cause crash.


In the machine with Kaveri processor, the COMPUTE=:0 set when logging in which allows running OpenCL programs remotely.  But this seem to cause segmentation faults at CodeXL if the client machine is using a non-amd gpu (at least so far that seems to be the pattern). If I unset COMPUTE then CodeXL executes fine but does not seem to detect the GPU in the kaveri machine.


Is this a known bug? or is there a workaround for this?
