[EDIT] Solved, PEBKAC.
First off, this is an amazing editor. Very impressed - thanks for your hard work on this project.
I'm seeing an issue on Ubuntu where bracket highlighting is behaving in a strange way. I have spoken to members in IRC, as well as confirmed myself, that this issue is not present on OSX. We have also confirmed this is not a theme issue, as it is present on multiple themes.
See the following screenshot:
This is my User/Base File settings. As you can see, all of the bracket matching is set to false. Still, brackets are highlighted with an overlay of sorts (the orange color). The highlighting occurs contextually based on cursor placement, so I'm guessing it is related to the "match_brackets_content" setting.
Is there something I am missing? Can this highlighting be disabled in some way? I'm finding that it is distracting when moving around a document.
Thanks in advance, please let me know if you need more information.
