Running 6.10.10.0 on Windows on host and Ubuntu 20.04.1 LTS
The control button works on and off, but the numpad has never worked properly. I have tried with number lock on and off, holding down the shift button also.
Thanks for your work developing the Linux client. Not sure if this has already been reported, however some keyboard keys are not responsive in the client or stop working sporadically. E.g. control key, number pad
