Bug 239557

Ubuntu 22.04 evolution 3.44.0 webkit2gtk 2.36.0 built with -DUSE_WPE_RENDERER=OFF mesa 22.0.1-1ubuntu2 including https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/15822 Test Case --------- From Ubuntu 22.04, open Evolution Click the New Email button Add text to the main textarea The text is invisible Workaround ---------- It works in the Ubuntu on Xorg session, just not the Wayland session. And this works: WEBKIT_DISABLE_COMPOSITING_MODE=1 evolution Other Info ---------- Evolution does display emails. It's just the composer that isn't working. This doesn't look reproducible with a standard Debian Testing or Fedora 36. Fedora 36 is also using mesa 22.0.1. Ubuntu had a previous issue triggered by mesa 22 that broke all webkit apps on Ubuntu ( https://bugs.webkit.org/show_bug.cgi?id=238513 ). That was fixed on Ubuntu with the mesa patch. Most distros build webkit with the WPE renderer option enabled but Ubuntu hasn't switched to that yet.
