Same here, with identical monitors at identical resolutions. The only difference is that one is using a DVI-VGA adapter. I see this whenever I open LibreOffice. The splash screen comes up on the secondary monitor and the application comes up on the primary. Using an ATI Radeon HD 5750. I tried modifying settings in compiz but no effect. Using 14.04 LTS. Same problem as in 12.04 LTS. Other applications will load on the primary but open dialogs on the secondary.
