On i915-based machines, any GTK4 app will crash on startup. I've encountered this on is a family member's desktop computer, a Dell Inspiron 530n, that sports an "Intel G33" graphics card alongside its Core2 Quad Q9300 CPU, according to GNOME Control Center in Fedora 35 (lspci says it's an Intel 82G33/G31 Express Integrated Graphics chip).
I saw that there is a Mesa 22.0.1 update scheduled down the pipe at https://bodhi.fedoraproject.org/updates/FEDORA-2022-4120f31977 but I *don't know* if the issue is actually fixed by that vs Mesa 21.x. If we are lucky it may be, if we are not then... it seems anyone running i915-based graphic drivers (and that probably means a _lot_ of people) will find Fedora 36 to be unusable because of the much more widespread presence of GTK4 (instead of GTK3) apps, that will refuse to run.
This was previously reported and partially troubleshot at (in chronological order):
I'm filing this here now "just in case" this flew under the radar and might turn out to be a release blocker.
Perhaps you have the means to test yourself (certainly someone in Red Hat's desktop/graphics team has older machines laying around) before F36's final release; I unfortunately cannot do so more extensively myself because, in part, of Anaconda's bug #2075608. I'm out of options at this point, and my current schedule means I won't be able to re-test that machine until at least mid-May, I think, so leaving it in your hands. I'm hoping the F36 final release liveUSB image has a potential fix for this (and the Anaconda issue) included, be it Mesa 22.0.1 or possibly other things on top, I don't know.
