Public bug reported: After running for a while, eventually the firefox window just becomes completely transparent. The window manager (gnome-shell) still sees it, and I can quit firefox. The dialog to ask me whether I want to quite with open tabs opens up, but is just a blank window. Thankfully I know where the "close tabs" button is and I click there and it works.
So, input events seem to work find and the window manager still sees the window, but it's gone. If I run firefox on the console I see this output when it happens: Unflushed glGetGraphicsResetStatus: 0x92bb [GFX1-]: [OPENGL] Failed to init compositor with reason: FEATURE_FAILURE_OPENGL_CREATE_CONTEXT There is an upstream bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1535721 that suggests looking at the value of layers.acceleration.force-enabled . Indeed it's set to true by default in this build. I'm running Pop!OS on a System76 laptop, but as far as I can tell from apt, the firefox package is just the ubuntu build. $ apt show firefox Package: firefox Version: 80.0.1+build1-0ubuntu0.20.04.1 $ firefox --full-version Mozilla Firefox 80.0.1 20200831163820 20200831163820 ** Affects: firefox (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/1896508 Title: Firefox window disappears completely To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1896508/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
