I've encountered a strange issue in 2217 regarding text selection with a mouse (Logitech Performance MX) on Linux (XMonad, Gnome 3 on Debian Sid, running on Virtualbox Windows 7 host).
When I click-drag with mouse on a single line, downwards, or upwards, the text window will scroll upwards, selecting text from the initial click to the current mouse position (or to the top of the text area depending on scrolling speed). The erratic scrolling makes text selection very difficult.
Similarly, when clicking on the minimap, and moving up or down with the mouse, the scroll bar will erratically jump to the top of scroll area then back to where the mouse is.
I've compared this on several VMs and it looks like it *may* be XOrg-related - 2217 does not exhibit the above on a vanilla Debian Squeeze install. At the same time, scrolling/text selection with mouse with Gnome 3's GEdit is not affected on Debian Sid...
Many thanks in advance!
