Warning messages in Dynare 4.4.3 output

As I execute Dynare 4.4.3 on Matlab 2016a, I get warning messages in the output.

I attach the output of example1.mod included in the Dynare program.
Are they innocuous and safe to ignore?

The first warning messages are due to Matlab’s new JIT compiler, see [Strange warning message). They can be safely ignored. To suppress them, you could use the

command line option. The second one about the graphics I haven’t seen before. It might be a problem on your machine with plotting. Does it always appear?

Thanks for your quick reply.
Your suggestion of “noclearall” command solved the first problem,
and upgrade of my graphics card driver as suggested in the Matlab message
solved the second problem.
