xfce4-panel coredumps immediately when starting unigine-heaven benchmark

Starting unigine-heaven triggers an immediate coredump of xfce4-panel. It occurs using the Arch Linux repo packages for xfce4 but I also built xfce4-panel-git and can confirm the coredump on it as well.

• Hardware: AMD X9950X, coredump occurs with using in chip GPU or when using a Radeon RX 560D with iGPU disabled in BIOS
• Graphics driver: xf86-video-amdgpu 23.0.0-2
• Distro: Arch Linux (rolling release distro, up to date)
• All xfce4 components are current from distro repos

Here is the backtrace, please let me know what else I can provide:
