I made a bug report in Ubuntu thinking its might be a Ubuntu/Canonical problem, but it doesn’t look like so:

I am thinking of using other alternatives of VMware. (Maybe Virtual Box)

This community looks barely alive. I DO NOT get a reply or solution or any form of tips. I have seen this on other questions too. It looks like its a common thing here.

Anyway, let me know what you guys think about Telegram not taking any keyboard & mouse input when I was using the latest stable Workstation Pro (with Kali Linux).
