Michael Jumper commented on GUACAMOLE-232:
------------------------------------------
Well ... you are not detecting stuck keys there - you are simply detecting
Guacamole's built-in key repeat, which is not a bug. Guacamole will
automatically repeat the keypress while the key is held down if the key is for
a printable character. The issue is not that the key is repeating, but that the
key release is somehow missed. From what you've described so far, Guacamole
must somehow either (1) not receive a corresponding keyup event for the
released key or (2) not recognize the received keyup as matching a pressed key.
Please try pressing the problematic key here:
http://guacamole.incubator.apache.org/pub/tests/key-event-test.html
and let us know what output is logged. The above is a generic JavaScript key
event tester which logs the details of received key events. It should,
hopefully, reveal why these keys are not properly handled for iPad+bluetooth.
