** Bug watch added: github.com/pop-os/pop/issues #1249 https://github.com/pop-os/pop/issues/1249 ** Changed in: firefox (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1896508 Title: Firefox window disappears completely Status in firefox package in Ubuntu: Invalid Bug description: 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1896508/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
