Thanks very much for answering. Yes, certainly that's the correct commit. I don't know what happened to the link; it got totally truncated... Here's again the complete whole link, this time split in 2 lines: https://gitlab.freedesktop.org/spice/spice/commit /ca4984570f425e87e92abe5f62f9687bb55c1e14 A "surgical" backport for this fix would be enough -I hope...- to test whether whole issue gets fixed or not. Thanks again.
