--- Comment #6 from Craig73 funrun73@gmail.com 2009-01-03 23:45:40 --- By turning on Compositing (Ubuntu - Appearence - Normal OR Ubuntu Tweak - Desktop - Windows - Enable Metacity's composting manager) that seems to correct the drawing of the box at the top and bottom of the evernote screen. (It is a gradient that is partially transparent to the notes below creating a shadow/fadeout at the top and bottom of the screen).
This box still sometimes disappears, but re-sizing the window can make it re-appear again (not sure if this is an issue within Windows) / it will be a separate WO if it is a WINE specific issue.
The fact this clipped region still shows up (and draws the gradient) on other windows even when this app is not foreground will be logged separately.
