This should be cherrypicked after merge because fix free camera that also affect 3.0.6 and 3.1 alpha.

There's also @moiman100's #20491 which is pending a merge and addresses a similar concern, so I'm not sure if we should merge both, or only one of them, or a mix of the two. Could you guys compare the two and see what the final outcome should be? :)

Also how does it work with #19191 if we were to merge that one too before or after this PR?

I tested #20491 for Linux and I think we shouldn't merge it, his changes doesn't look good when using get_global_mouse_position or get_viewport().get_mouse_position(). See here:

global position should not be moved in captured mode.

My PR already fix #20491 and I'm also fixing confined mode.

You can merge both in this case, both are needed (but one don't depend of the other). I already tested local with both PRs and it should not generate any conflict (the order doesn't matter).

Thanks for testing. Let's merge this one then :)

Now that Godot 3.1 has been released, we only plan to cherry-pick critical bug fixes to the 3.0 branch, unless there is very strong support in favor of a specific non-critical issue. Removing cherrypick label for 3.0.
