I'm having this same issue since upgrading to 10.10. I'm using a Radeon 4850 with the proprietary fglrx drivers so I do believe it's definitely not a video card issue. I've attached a quick video illustrating the problem with dropdown menus. Submenus act the same way. I also find with submenus, however, that if I click three times (which would be the equivalent of show, hide, show) on one that isn't showing properly, it fixes it for that menu as well.
I also notice this problem with Eclipse, but it only affected submenus in that. It seemed to affect ~100% of the submenus in Eclipse, however, but in other apps it's maybe 30%. I tried using metacity with compositing, but had the same issue. I also tried, before that, disabling compiz plugins one at a time to see if I could pinpoint any specific one causing it. Again, no luck. Anyway, hopefully the video illustrates the problem a bit more clearly. ** Attachment added: "Menu-Bug-665546.ogv" https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/665546/+attachment/1729087/+files/Menu-Bug-665546.ogv -- Drop and sub menus don't always show up https://bugs.launchpad.net/bugs/665546 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
