A very important detail: Ubuntu builds webkit2gtk with -DUSE_WPE_RENDERER=OFF This was done because we would need Ubuntu Security Team sign off to get wpewebkit in to Ubuntu's 'main' archive section instead of in 'universe'.
It looks like this bug is specific to that config. Copying from the mesa bug: https://gitlab.freedesktop.org/mesa/mesa/-/issues/6236#note_1329402 "The issue is that WebKitGTK's internal Wayland compositor needs to implement zwp_linux_dmabuf_v1 rather than relying on EGL_WL_bind_wayland_display. In the meantime, we could revert the part which makes us strictly rely on dmabuf on the Mesa client side, and keep both in parallel for a little bit. But WebKitGTK should really be implementing this interface." -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1966418 Title: [jammy regression] webkit apps do not display content (yelp, epiphany, gnome-online-accounts etc) Status in Gnome DevHelp: Invalid Status in Mesa: Unknown Status in Webkit: Confirmed Status in epiphany-browser package in Ubuntu: Invalid Status in evolution package in Ubuntu: Invalid Status in gnome-control-center package in Ubuntu: Invalid Status in liferea package in Ubuntu: Invalid Status in mesa package in Ubuntu: Confirmed Status in webkit2gtk package in Ubuntu: Confirmed Bug description: Impact ------ All webkit using apps for affected users display a blank screen. Original Bug Report ------------------- Evolution has suddenly stopped displaying message contents on the last 24h. Starting it up from the command line shows this output: ``` EGLDisplay Initialization failed: EGL_NOT_INITIALIZED Cannot create EGL context: invalid display (last error: EGL_SUCCESS) ``` I don't know if it's related, but googling around shows some webkitgtk hits on this error. The email contents are however clickable. They're just not rendered to screen (see attached file). Deleting the evolution folders from `~/.config`, `~/.cache` and `~/.local/share` does not help. Email accounts are all google, configured through gnome online accounts. Workaround #1 ------------- You can run the app from the command line with WEBKIT_DISABLE_COMPOSITING_MODE=1 evolution (Replace evolution with the name of the webkit app you are trying to use) Workaround #2 ------------- Log out. Select your name on the login screen. Click the gear button and choose Ubuntu on Xorg. Enter your password to finish logging in.
