Hello, I just want to let you know that the Linux buid is (at least on my system), unable to handle any mouse events, as soon as the main game menù (not the UnityEngine one) is displayed.
If you can point me to the location of an output log file, I will be happy to post its contents if it can help you inspect this problem (which, by the way, I've experienced many times with Linux builds created with old UnityEngine versions, not with more recents ones instead like from 2018-2019).
Thanks.
