After starting Eddie I have to leave the window open and also to not resize or minimize.
If i do any of the above I Eddie becomes a blank window, i can still access the toolbar to shut down. Clicking the Air Eddie icon in Ubuntu's tool bar (where the volume and power buttons are) can sometimes bring it back to normal.
If I try to change option tab in Eddie sometimes parts of the previous tab will show on the active tab.
Attached is an example where I resized the window, changed tab to servers and then back to overview. The server view is partly visible.
