Ok, so this doesn't have anything to do with Stardock's stuff, but I still thought it might be a good idea to ask here.
I'm trying to theme my TotalCMD in the same way as Sublime on right:
TC's seems to be rendering the marked "no good" borders by itself, so it's not an OS-governed thing
And for this reason, I assume the only way to edit these is by hacking the relevant lines of code (or similar).
Can anyone help with this?
I'd do it myself, but I don't even know how to figure out what renders these borders with certainty.
