I get what might be a variant of this bug. A white window or box appears covering the page display area but none of the UI in chromium.
My problem seems unrelated to either notifications or Flash; for example, it can appear when using the "Open Image in New Tab" context menu item. It always appears on the initial page load. Despite the white box, I can Alt+Click to drag windows out of the covered area and interact with things underneath; they're just not visible. Logging out, then back in is the only way to make it disappear. Attaching two screenshots. ** Attachment added: "Screenshot from 2012-03-07 22:29:37.png" https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/940603/+attachment/2860361/+files/Screenshot%20from%202012-03-07%2022%3A29%3A37.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/940603 Title: white box randomly shows up at top left corner blocking applications from using stuff under it To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/940603/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
