Can you try running
find /usr/ -type f -print0 | xargs -0 grep -H imprecise_trapezoid_span_converter

Interesting!
This suggests your intel driver is rather new and has this bug, as on my systems (Kubuntu
LTS) intel_drv.so does not have references to imprecise_trapezoid_span_converter. In fact
it is so bleeding edge that Google does not show hits to repository with
"imprecise_trapezoid_span_converter".
Looks like intel driver contains two bugs: whatever triggers the assertion, and
assertion that when violated exits X-server. It is likely a
drawing code, so it could just draw nothing.
I would suggest first to check RedHat changelogs to see where the code came
from and whether they backported any patches. It could be the error occurred
during porting. If this is not the case, then contact intel_drv developers,
which I think is Intel - they should have forums to post a question to.
Looking at my backup from early Jun (just before the upgrade to f42) I see this
driver:
-rwxr-xr-x 1 root root 1626800 Jan 27 2024
tmp/xorg/usr/lib64/xorg/modules/drivers/intel_drv.so
It is old, and I do update regularly. It starts with this stanza (using strings
-a)
{"type":"rpm","name":"xorg-x11-drv-intel","version":"2.99.917-57.20210115.fc40","architecture":"x86_64","osCpe":"cpe:/o:fedoraproject:fedora:39"}
The one I have now is much larger
-rwxr-xr-x 1 root root 2157928 Jan 19 11:00
/usr/lib64/xorg/modules/drivers/intel_drv.so
It arrived when I did the f40->f42 upgrade on 2/Jun. It end with this stanza
(using strings -a)
{"type":"rpm","name":"xorg-x11-drv-intel","version":"2.99.917^20240506gitce811e7-63.fc42","architecture":"x86_64","osCpe":"cpe:/o:fedoraproject:fedora:41"}
This is a large jump, I suspect the newer driver includes many changes.
