But I don't see where to change the actual color code for matching brackets, is this not supported yet?
Found it, It's in Color Scheme - default directory
I use iPlastic right now for my color scheme, I can't find it anywhere in the packages directories.  Where would I edit the color scheme so I can change the matching brackets colors?
Yes I can confirm Linux issue as well, doesn't seem to happen on Windows, one other user reported it was a problem on OSX, but hasn't responded to his version yet.
This was just added in the latest build
