Public bug reported: Binary package hint: metacity
Window corners are round, so there is a little bit of transparency in the corner. To establish this transparency effect, metacity shows the wallpaper underneath the 'transparent' part of the corner in the transparent part of the corner. But the gnome panel (when on top) drops a shadow on top of the wallpaper and because there is no real transparency this shadow isn't shown in the window corner. As a result you can clearly see the contrast between the window corner and the wallpaper. I included a screenshot. metacity 2.30.3 Fully updated Ubuntu 11.04, running in Ubuntu Classic mode (simply without unity) ** Affects: metacity (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/793284 Title: Window corner fake transparency problem -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
