I can reproduce the issue with GTK3: Menu Bar | Tool Bar | Time (1st run) | Time (2nd run) ---------+----------+----------------+--------------- yes | yes | 187 secs | 116 secs yes | no | 90 secs | 8 secs no | yes | 204 secs | 124 secs no | no | 89 secs | 8 secs It seems that the presence of a tool-bar slows down scrolling significantly. Especially, scrolling for the second time is always fast unless there's a tool-bar. Bye, Tassilo
