I'm experiencing the same thing, and only in Yelp. I have an ATI X300. At first I thought it might be due to using RGBA enabled GTK+, but I reverted to the Lucid version and the problem persists.
There are a couple of things to note in the screenshot (which I was able to take by moving focus to another window). 1. There's no scrollbar (it should look like the one in the terminal window). 2. There's a tear at the bottom of Yelp right below the information box. ** Attachment added: "Screenshot-1.png" https://bugs.launchpad.net/ubuntu/+source/yelp/+bug/543626/+attachment/1512568/+files/Screenshot-1.png -- The Help Browser is BROKEN. Scrolling up and down creates tearing, and it does not draw correctly. Thereby making the Help Browser broken and worthless. https://bugs.launchpad.net/bugs/543626 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
