Hello, a workaround that I have discovered is to disable framebuffer objects in the Compiz OpenGL plugin:
gsettings set org.compiz.opengl:/org/compiz/profiles/unity/plugins/opengl/ framebuffer-object false Enter that in the terminal and it would take effect immediately; no logout required. Of course, we can expect that other desktop features that absolutely need OpenGL framebuffer objects might glitch or be affected in some way. And again, this is just a workaround to make the unsightly behaviour go away, and by no means a fix. It does give a clue, though, that it's related to the use of framebuffer objects by whatever it is that renders shadows and glow effects. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1467695 Title: Alt-Grave (`) switcher has flickering/pulsing shadow artifacts To manage notifications about this bug go to: https://bugs.launchpad.net/nux/+bug/1467695/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
