Hi Pavel, Yes, in my configuration I have already set:
vram: 64MB streaming mode='filter' <-- I have tested with 'all" as well with the same results image compression='auto_glz' When I connect through the Internet or from my home wi-fi (54Mbps) In the logs I can see "LOW BANDWITH" detected, and the video performance is really bad. Thanks a lot. 2017-03-09 13:14 GMT+01:00 Pavel Grunt <pgr...@redhat.com>: > On Thu, 2017-03-09 at 06:43 -0500, Frediano Ziglio wrote: > > > > > > It's not a small addition.
