devrandom commented on GUACAMOLE-232:
-------------------------------------

I tried to debug this by modifying  "$scope.$on('guacKeydown', function keydownListener" in
./guacamole/src/main/webapp/app/client/directives/guacClient.js

{code}
                var last = Date.now();
            // Translate local keydown events to remote keydown events if keyboard is enabled
            $scope.$on('guacKeydown', function keydownListener(event, keysym, keyboard) {
                if ($scope.client.clientProperties.keyboardEnabled && !event.defaultPrevented) {
                now = Date.now();
                diff = now-last;
                console.log(diff)
                if (diff < 55 )
                {
                        console.log("Stuck detected for:");
                        console.log(keysym);
                        client.sendKeyEvent(0,keysym);
                        client.sendKeyEvent(0,32);
                                client.sendKeyEvent(0,65288);
                                client.sendKeyEvent(0,65293);
                            event.preventDefault();

                        last = Date.now();
                        return;
                }else
                {
                last = Date.now();
                }


                    client.sendKeyEvent(1, keysym);
                    event.preventDefault();
                }
            });

{code}

Stuck key get's detected, but loop continues although I suppress the keydown events by only sending key up events. So  I think the loop is created before this function is called. Any ideas how I could investigate this further?

> I have the same issues as described in:
> https://glyptodon.org/jira/browse/GUAC-661
> Which theoretically was solved in 0.9.7.
> After some typing using iPad with connected bluetooth keyboard, the following Keys may get stuck.
> * return
> * space
> * backspace
> Attached you'll find an example using xev on linux.
> Guacamole produces keyup and keydown events in a loop.
