* bug 1709584 blocked enabling EGL/X11 in Ubuntu 18.04 CI.
* FEATURE_DMABUF (bug 1572697): No problems known yet.
* [WR/Xwayland](https://searchfox.org/mozilla-central/rev/a3a9112d4d73d1323eabbc7faa9937cd9aae6465/widget/gtk/GfxInfo.cpp#702) could be lowered as well.
  * [partial present](https://searchfox.org/mozilla-central/rev/a3a9112d4d73d1323eabbc7faa9937cd9aae6465/widget/gtk/GfxInfo.cpp#815) (supported on X11&Xwayland since Mesa 20.2) would cause bug 1677892 on Xwayland < 1.20.10.
    * Requiring Mesa 21 for partial present on Xwayland wouldn't hurt, but also wouldn't help if a user would manually compile latest Mesa on Ubuntu 18.04.
    * Ubuntu, Debian and Fedora don't seem to have affected package version combinations anymore.
