Hi all, This week we identified an issue introduced to upstream Mono which severely impacts Linux Editor Beta users using Experimental Mono. As far as I can tell, this applies to all versions of the Linux Editor Beta. The issue will usually manifest itself as an error in your Console where background jobs will fail, e.g. Enlighten baking, shader compilation failures, and so on. However, it's likely there are more stability implications that go beyond these error messages, such as random crashes and other unexpected behavior. We're currently verifying a potential fix with the Mono Project and our own QA. You will need to switch to stock Mono in the Project Settings and restart your Editor for the changes to take effect. However, be cautious, because any Experimental Mono features your projects make use of will no longer function correctly. Thanks.
