I'm not sure what extension is painting the "Comment Bubbles" seen in this screenshot.
I've gone through the extensions that I knowingly installed and do not see an option to turn it off. Either it's coming from an extension I don't know about, or it's an option in one of the ones I looked at but missed. Any help would be appreciated.
It's devExpress. Go to DevExpress-> Options
Expand Editor -> Painting and then go to Comment Painter. Uncheck enabled.
