Seeing the same issue here using the KRDC frontend. I can also confirm that this problem was introduced in Edgy; I never saw it on Dapper. For me, however, the corruption occurs whenever I scroll up, regardless of the speed I scroll at.
I'm including another screenshot, because I'm not sure this is the same issue that Gilbert is having. I see artifacts only when scrolling up and the artifacts appear only inside the viewport being scrolled. Also scrolling left or right always works. ** Attachment added: "Scroll artifacts" http://librarian.launchpad.net/4967351/rdesktopscrollup.png -- Redraw errors on rdesktop 1.4.1-1.1 (edgy) https://launchpad.net/bugs/68583 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
