On networks with high latency, typing fast characters are entered twice

[sergio]

On a network with a good throughput, but a high latency (connection via a mobile phone), I am experiencing a strange phenomenon.

When typing on the keyboard, if I type slowly everything is fine.
However, if I type fast, some keys get repeated. For instance, trying to type:

echo This is a test

I may get

eccho Thiis iis a teest

man xpra | grep latency

Edited grep:

       --no-keyboard-sync
              Disables keyboard state synchronization. Normally the key presses and key release events are sent to the server as they occur so that the server can maintain a consistent keyboard state.  Using this option can prevent keys from repeating unexpectedly on  high
              latency links but it may also disrupt applications which access the keyboard directly (games, etc).

Let me know if that helps..

Thanks... I have evidently missed it...
I'll try as soon as have that kind of high latency access again.
Would be great if this could be self-tuning.

OK, once tested - please close the bug if this works for you.

Self-tuning would be great.. but latency is hard to measure, and by definition it fluctuates, so this is going to be difficult. What we could do, which would help us to bring self-tuning eventually would be to at least provide a GUI option for it so it can be toggled at runtime without disconnecting: moved to #143

not heard back, closing
