All webkitgtk using apps just show a blank webview (either light with a light theme or dark with a dark theme). The cursor does change when hovering over invisible links. When run from the command line this shows: EGLDisplay Initialization failed: EGL_NOT_INITIALIZED Cannot create EGL context: invalid display (last error: EGL_SUCCESS) This only happens when logged into a GNOME/Ubuntu on Wayland session. Either running in an Xorg session or with the WEBKIT_DISABLE_COMPOSITING_MODE=1 prefix works around the problem. Other Information ================= I believe this bug was triggered by the recent upgrade to mesa 22.0. I think it might only affect Intel graphics. My system according to GNOME has Intel® Core™ i5-10310U CPU Mesa Intel® UHD Graphics (CML GT2) Reply at: https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/1966418/comments/36 ------------------------------------------------------------------------ On 2022-03-29T18:51:21+00:00 Michael Catanzaro wrote: > I believe this bug was triggered by the recent upgrade to mesa 22.0. Huh, here on Fedora 36 I only have mesa 21.3.8. Is it possible to downgrade mesa to confirm that the mesa upgrade is to blame? That would help a lot.

Note that there are two drivers: the traditional “i965” and the new “iris” driver. Here I am using “iris” (and there is not even the other installed). You can set “MESA_LOADER_DRIVER_OVERRIDE=iris” if your GPU is supported by the new driver and if things then work that will mean that the issue is most likely the i965 driver. Alternatively, if Iris driver does not support your GPU but Vulkan is supported, you can try the “zink” driver, which implements OpenGL and GLES on top of Vulkan (and again, if that works, then there is some bug in the Intel driver you are using :D) I hope this helps!
