I saw many situations with this problem with different applications (for example with MonoDevelop + Evolution, Evolution + Firefox etc). It is hard to reproduce, but I found a one stable (for my system) situation:
1. Boot system.
2. Start Evolution (I'm starting via left-side Unity panel or via envelope at the top panel, there is no difference).
3. Click any hyperlink in the letter inside Evolution.
4. Firefox opened correctly. Minimize it (I'm using a mouse).
5. Click any (may be same link as in p.3) hyperlink in the letter inside Evolution.
6. Firefox maximizes in incorrect way (see picture). Also we can see a strange blue triangle at the left top corner.
