Hi,
I also have this issue:
Upgraded to 15.5.5 build-16285975 a couple of days ago and then noticed the caps lock issue in the following hosts:
Kali 2020.2
Ubuntu 20.04 LTS
Host: Dell Inpsiron 15-5577
Win 10 home 1903
8GB
Intel CoreI i7
As well as caps lock refusing to turn off (or on), and the intermittent case flipping whilst holding a key down, I also noticed:
In the Ubuntu password entry logon screen, pressing caps lock once results in the "caps lock is on" message, but no caps lock light. Pressing caps lock a second time causes the 'caps lock is on' message to flicker for several seconds before finally stopping on 'on'. pressing it a third time causes it to flicker.... well, i get bored before I see it stop, if it stops.
The vmx edit workaround works for both guest OS's.
