Description Jeremy Bicha 2022-04-20 11:19:31 PDT 
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.

evolution changes related to bug #239429 may address this one too - evo disables hardware acceleration in the code again.
