Public bug reported: After the delivery of plasma 5.11.3 via the kubuntu backports ppa (ppa :kubuntu-ppa/backports), firefox is completely unusable.
Seen on two different machines, one with intel graphics (haswell) and one with nvidia quadro FX570 using the nouveau driver. Firefox cannot be used unless compositing is turned off in kwin, so I suspect an issue in the latter. Specifically, all firefox buttons that are expected to open a window (e.g., the main menu button, the bookmark button, most of the extensions button) do not, making the browser limited to mere browsing (no bookmarks, no advanced actions driven via the menu, no extensions). The two machines where I see the issue have in common the use of mesa as the opengl provider (latest mesa in fact). I do not have the option to try with proprietary graphics drivers. Please, provide a way to go back to 5.11.2 without removing the KDE backports altogether. ** Affects: kubuntu-ppa Importance: Undecided Status: New -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to Kubuntu PPA. https://bugs.launchpad.net/bugs/1731767 Title: Plasma 5.11.3 breaks firefox To manage notifications about this bug go to: https://bugs.launchpad.net/kubuntu-ppa/+bug/1731767/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
