Hi All,
spice-gtk commit 0d5ad7e22d55552ef4be8368dcfbae879fb0b77e (widget:
differentiate key press & release from press only events) introduced a
short delay in sending key press events, which was designed to reduce
unwanted key repeat.
However, on low-latency networks, this delay (default is 100ms) is quite
noticeable and causes a "laggy" feel when using spice.
Currently I have recompiled spice-gtk with a 10ms delay and the overall
feel is MUCH improved. It's quite shocking how such a small thing can
have such a large effect.
The actual delay used is a property in the spice widget, but is not
exposed as a user controllable value (afaict), nor is the value
automatically adjusted by, say, the RTT to the spice server.
I'd like to, at the minimum, add a "---spice-keypress-delay <n>"
argument to remote-viewer, but in today's world, exposing settings to
users is practically forbidden, so I'm doing a temperature check before
I do anything. The alternative would be to auto-tune the value. If the
auto-tune route is the way to go, I can come up with some ideas, but
that can stay on hold.
Thoughts?
