I have an HD 5870. I'm not using any additional or proprietary drivers (according to that tab in Software & Updates); however, 'Proprietary drivers for devices' is enabled in the Ubuntu Software tab in Software & Updates.
The only PPAs I have are for Google Chrome, PlayOnLinux, and Alexander Larsson's Launchpad. For my video card information: Cypress XT [Radeon HD 5870] Vendor: AMD/ATI Phys. ID: 0 version: 00 clock: 33MHz driver: radeon I'm not sure exactly which information you need, so here is a pastebin of the output of 'modinfo radeon': https://pastebin.com/axFRR5hw. I'm honestly not sure what to provide, so if you want the output of some commands, I can provide those easily if you tell me which/what you'd like. I didn't find any GUI-level information on my drivers or what packages they are, so that's the best I could find in the time I have for this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767648 Title: Top bar and shell dialogs are not displayed properly when zoom is enabled To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1767648/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
