++ This bug was originally reported in https://bugzilla.redhat.com/show_bug.cgi?id=1286808 ++ Description of problem: Intermittently keys are getting "stuck", using remote-viewer v2.00 and spice-gtk 0.30. I think the issue is similar to the following bug reports: https://bugzilla.redhat.com/show_bug.cgi?id=1086650 https://bugzilla.redhat.com/show_bug.cgi?id=812347 The main difference being that it happens on a low latency/low jitter network, and the keys getting stuck are primarily modifier keys (CTRL the most, sometimes ALT & SHIFT). The most common case is using CTRL+C/CTRL+V to copy/paste, and the CTRL gets stuck or the "C" gets stuck. Latency/Jitter example (local gigabit network): PING 10.7.5.11 (10.7.5.11) 56(84) bytes of data. 64 bytes from 10.7.5.11: icmp_seq=1 ttl=64 time=0.222 ms 64 bytes from 10.7.5.11: icmp_seq=2 ttl=64 time=0.191 ms 64 bytes from 10.7.5.11: icmp_seq=3 ttl=64 time=0.205 ms 64 bytes from 10.7.5.11: icmp_seq=4 ttl=64 time=0.198 ms 64 bytes from 10.7.5.11: icmp_seq=5 ttl=64 time=0.200 ms 64 bytes from 10.7.5.11: icmp_seq=6 ttl=64 time=0.161 ms 64 bytes from 10.7.5.11: icmp_seq=7 ttl=64 time=0.121 ms 64 bytes from 10.7.5.11: icmp_seq=8 ttl=64 time=0.183 ms 64 bytes from 10.7.5.11: icmp_seq=9 ttl=64 time=0.130 ms 64 bytes from 10.7.5.11: icmp_seq=10 ttl=64 time=0.192 ms --- 10.7.5.11 ping statistics --- 10 packets transmitted, 10 received, 0% packet loss, time 8997ms rtt min/avg/max/mdev = 0.121/0.180/0.222/0.032 ms Version-Release number of selected component (if applicable): remote-viewer v2.00 spice-gtk 0.30 How reproducible: Unfortunately we can't reproduce it at will, but it seems to happen about 1-3x per day, even with "xset r off" on the client. Previously when using spicec or remote-viewer v1.00 and spice-gtk 0.28 it seemed to happen around 4-6x per day and with more than just the modifier keys. However since upgrading to remote-viewer v2.00 and spice-gtk 0.30 it has reduced the occurrences significantly. Usually tapping the key that got stuck a few more times seems to "unstick" it.

Can you try setting SPICE_KEYPRESS_DELAY to 0 (it's an environment variable) ?
