I assume you mean the scrollbars on the editor pane. These are drawn by the Scintilla editing widget Geany uses. AFAICT [Scintilla](https://www.scintilla.org/ScintillaDoc.html#ScrollingAndAutomaticScrolling) has no settings Geany can control to change the speed.
But I suspect that it is following your desktop theme, you could try setting something there. -- You are receiving this because you are subscribed to this thread. Reply to this email directly or view it on GitHub: https://github.com/geany/geany/issues/1904#issuecomment-407572258
