Lots of great GNU/Linux improvements with the latest Unity release: https://blogs.unity3d.com/2019/04/16/introducing-unity-2019-1/ Will we get this with R65? (Please)
I believe no, they need a drama free release. So they will try for 66. That's if I heard right on today's twitch stream. I think he talks about it somewhere between minutes 15 and 30,but could be a little later.
QA did not have all those weird bugs tho, yes the ground textures were too dark and some renderings were squares. But most of the big bugs in release were mess up from the devs "trying" to fix the dark ground texture really.
