Ach! It's the FGLRX graphics driver, or maybe an Xserver bug enabled when fglrx is used. Switching to the free driver made the problem go away.
Using fglrx the hollow-thick-line problem is constant at 1920x1280 screen res, but at 1280x1024, the top thick line in the demo is black about half way across, then hollow, and expose events (to re-paint regions when un-covered) always seem to re-paint as hollow. The detailed manner in which the X server sends expose events to an application may be affected by the driver and the details of hardware acceleration and caching of save-unders, etc., so this may still be an Open Office bug (but I'm not an expert in X, so this is speculation). But it may well be just a bug in the graphics driver. OTOH, I don't see such symptoms with any other application. P.S. Thanks for the pointer to 'testdrive' . I use VirtualBox, though. -Jim -- Thick border appears hollow in Print Preview https://bugs.launchpad.net/bugs/559579 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
