This problem also occurred to me using a fresh install of Ubuntu 22.04. Firefox throws an error: glxtest: Could not connect to wayland socket
Firefox falls back to xwayland. I noticed it as all the text was unsharp using fractional scaling. The problem also occurred when removing firefox snap and installing it as flatpak. Using firefox-esr (91.8) as snap solves the problem. -- 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/1970615 Title: WebGL does not work in snap firefox Status in firefox package in Ubuntu: Incomplete Bug description: Since upgrading to Ubuntu 22.04 LTS I am no longer able to use WebGL on firefox. If I go to https://get.webgl.org/ it says "Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card." This is the case on my laptop with Intel HD4600 Graphics and on my desktop with AMD Vega 56 Graphics. Both are on Ubuntu 22.04 LTS with snap firefox. troels@troels-thinkpad:~$ glxinfo | grep OpenGL OpenGL vendor string: Intel OpenGL renderer string: Mesa Intel(R) HD Graphics 4600 (HSW GT2) OpenGL core profile version string: 4.6 (Core Profile) Mesa 22.0.1 OpenGL core profile shading language version string: 4.60 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.1 Mesa 22.0.1 OpenGL shading language version string: 1.40 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.2 Mesa 22.0.1 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20 OpenGL ES profile extensions: I therefore have to use Chrome instead for developement using three.js To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1970615/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
