I ran QSG_RHI_BACKEND=software rkward with 0.8.2 from
rkward-0.8.2-1.fc43.x86_64, and the first type of crash happened. I previously
booted with nomodeset on the kernel command line to use the llvmpipe mesa
driver and simpledrm kernel driver, and the problem also happened. So the
problem wasn't specific to the radeonsi and amdgpu drivers I normally used.
There might be some incompatibility in qtwebengine between Qt 6.10.0 and
6.10.1. Should I reassign my report of this problem at
https://bugzilla.redhat.com/show_bug.cgi?id=2416541 to qt6-qtwebengine? There
have been reports of the Qt 6.10.1 update in Fedora 43 causing different
problems with plasma-workspace
https://bodhi.fedoraproject.org/updates/FEDORA-2025-b332f482fa which required a
rebuild https://bodhi.fedoraproject.org/updates/FEDORA-2025-614a882af4  Thanks.
