Re: Was the initial graphics mode screen removed?
Please open an issue with the details of your machines that crash when
trying to use accelerated graphics. We thought that we had addressed all
or almost all of these cases.
Our current plan is to shift our backend graphics away from the
OpenGL/Cairo engines and use a third-party library like libbgfx. This may
remove any option for Cairo rendering in the future, so it'll be good to
work out the kinks.
And for the peanut gallery: of course we check libraries and query features
before using them. The segfaults happen when libraries return values that
they don't actually support. Mesa/X11 is a big culprit here on Linux and
older bulit-in intel drivers on Windows do the same. The way we do better
is to get detailed system reports when segfaults happen. If folks just sit
on these issues because fallback works for them, then we'll never fix them.
