Hello all, I have a guacamole server running VNC into Proxmox KVM VNC servers. This works fine except for an issue with some keys appearing to be stuck down.
Pressing either shift key works as expected for "standard" characters (a-z) and some special chars (shift 1-9 and a few others). However for some keys, such as Shift-\, Shift-' the key is repeatedly typed into the VM until the key is pressed again. Running xev in the VM shows the keydown and keyup events for the shift keys and normal keys, but the 'stuck' key shows as being repeatedly sent to the VM until pressed again. The current workaround is to disable repeat keys in each VM but this still doesn't fully behave properly as the key will then appear to be not working until pressed again. I have tried different browsers, different operating systems (both on the client and on the VM side) and this has continued to occur across Proxmox and KVM major updates.
