Tomas is right. A workaround discussed in duplicate bug 1072889 is to turn on: CCSM > Composite > Unredirect Fullscreen Windows
But, WARNING: That's only safe to do on 12.10 or later. 12.04 has bugs in the nouveau and intel drivers that will be triggered and often crash the whole X server. It's not really a problem for nvidia, radeon, or fglrx. Also note that this option is turned on by default starting in 0.9.8.6 for quantal and 0.9.9.0 for raring. ** Summary changed: - SDL applications bad resizing + Fullscreen windows at lower than native resolution only show upper left corner ** Package changed: unity (Ubuntu) => compiz (Ubuntu) ** Also affects: compiz Importance: Undecided Status: New ** Changed in: compiz Status: New => Confirmed ** Changed in: compiz Milestone: None => 0.9.9.0 ** Changed in: compiz Importance: Undecided => High ** Also affects: compiz/0.9.8 Importance: Undecided Status: New ** Changed in: compiz/0.9.8 Importance: Undecided => High ** Changed in: compiz/0.9.8 Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069536 Title: Fullscreen windows at lower than native resolution only show upper left corner To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1069536/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
