Incosistent behaviour in DTTG scrolling pdfs in edit mode


Recently there has been an issue with DTTG while looking at PDFs in edit mode. Normally when the highlight button is active, I can scroll with my fingers and highlight only with the pencil. Recently, attempting to scroll with my fingers results in highlighting text. Seems like a bug because at some point it went back to normal (highlight only with pencil), but becomes messed up again. I’m still not sure what causes this behaviour to appear and disappear.

Just to reiterate: I am in edit mode and highlighting is active, normally only the pencil should highlight while fingers scroll, but at times both pencil and fingers result in highlighting.
