I have this problem too - even on web pages with dropdown menus. I've had this problem for a long time, definitely in Ubuntu 10.04 as well as 10.10 but then I get the latest unstable updates so may have gotten whatever was causing the problem early while still using 10.04.
I don't use compiz. I had the problem with compositing turned on for metacity, and also with mutter that I use now. I've had this problem on 3 different computers, all using the proprietary Nvidea driver. I also have a problem with office applications not always displaying the window when opened. Specifically Open Office (now using Libra Office and still have the same problem) and also GnuCash. Usually works fine the first time I start one of these apps after logging in, but if close the app and try to open it again a while later, nothing shows up. I have to kill the process from System Monitor and then try to open it again. That usually works, but sometimes I have to log out and back in. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/665546 Title: Drop and sub menus don't always show up -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
