I am getting this error when I attempt to run code on 2 of 3 computers:
[0502/155335.565:ERROR:gpu_process_transport_factory.cc(1007)] Lost UI shared context
I had the same problem. Try adding these flags to Chrome driver options:
options.add_arguments("--proxy-server='direct://'"); options.add_arguments("--proxy-bypass-list=*");
See this link for more information.
