Ok, thanks for the explanation.

Doing more testing I was able to run a good remote debug session only
if I started gdbserver in the target device by X forwarding i.e. from
host PC running command:
ssh -X user at rpi.local gdbserver --multi :10000

I don't know how to see the exact command QtCreator uses to start
gdbserver, I can only see:
Starting gdbserver --multi :10000...

If using ssh as I do, could it be possible to add the -X modifier
given that the Run configuration in effect when starting debug session
(F5) has option "Forward to local display" checked

Regards. Pablo
