Summary: kwin_wayland crashed in convert_ubyte_rgba_to_bgra
Classification: Plasma
Product: kwin
Version: 6.1.1
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: qt6
Severity: normal
Priority: NOR

SUMMARY
I booted the Fedora Rawhide KDE live image
Fedora-KDE-Live-x86_64-Rawhide-20240704.n.0.iso in a QEMU/KVM VM in GNOME Boxes
with 3D acceleration enabled using the virgl driver from mesa 24.1.2 and
virtio-gpu from the 6.10.0-0.rc6.20240703gite9d22f7a6655.53.fc41 kernel. Plasma
6.1.1 on Wayland started. I started Konsole. I ran sudo dnf upgrade
https://kojipkgs.fedoraproject.org//packages/selinux-policy/41.7/1.fc41/noarch/selinux-policy-41.7-1.fc41.noarch.rpm
https://kojipkgs.fedoraproject.org//packages/selinux-policy/41.7/1.fc41/noarch/selinux-policy-targeted-41.7-1.fc41.noarch.rpm
The upgrade took a few minutes because the selinux-policy-targeted-41.7-1.fc41
post-install scriptlet looked like it was relabelling the / filesystem with
restorecon. I might've run journalctl --no-host in another Konsole tab while
the update was happening. The VM's screen went black. drkonqi appeared. I
clicked Developer information. I selected to automatically download debug info
in drkonqi and reloaded. The debuginfod data filled the 1.7 GB / partition
completely so I deleted it. I installed the kwin, mesa, qt6-qtbase debug info
packages manually. I unselected to automatically load the debug info and
reloaded the trace, but drkonqi showed the debuginfod file downloads and the /
partition ran out of space again. I closed drkonqi. gdb crashed and the
kwin_wayland core dump was automatically removed. coredumpctl info showed that
kwin_wayland 6.1.1.2 crashed in convert_ubyte_rgba_to_bgra in virtio_gpu_dri.so
likely in virgl in mesa. The trace seems to involve the virgl driver converting
a texture image from rgba to bgra, so the problem might be in mesa.

ELF object binary architecture: AMD x86-64
I tried to reproduce the problem but it didn't happen. I'll try again to get a
trace with debug info.
STEPS TO REPRODUCE
1. boot the Fedora Rawhide KDE live image
Fedora-KDE-Live-x86_64-Rawhide-20240704.n.0.iso
https://koji.fedoraproject.org/koji/buildinfo?buildID=2482412 in a QEMU/KVM VM
in GNOME Boxes with 3D acceleration enabled in a Fedora 40 KDE installation
2. start Konsole
3. Run sudo dnf upgrade
https://kojipkgs.fedoraproject.org//packages/selinux-policy/41.7/1.fc41/noarch/selinux-policy-41.7-1.fc41.noarch.rpm
https://kojipkgs.fedoraproject.org//packages/selinux-policy/41.7/1.fc41/noarch/selinux-policy-targeted-41.7-1.fc41.noarch.rpm
4. Open a new Konsole tab
5. run journalctl --no-host in the second Konsole tab and scroll up and down
the journal
6. If the problem didn't happen, repeat 1-5 until it does. I don't know which
of 2-5 are related to the problem, if any.
OBSERVED RESULT
kwin_wayland crashed in convert_ubyte_rgba_to_bgra
EXPECTED RESULT
kwin shouldn't crash
