supertuxkart crashes weston on weston-rdp with zink
I'm testing on SM8650 (with Adreno a750 GPU) with zink + turnip. Basic vulkan demos work, glxgears on zink works, but supertuxkart when run via wayland (the default at least on the version I've got from fedora) results in weston with the rdp backend segfaulting with this backtrace:

Running via X11/XWayland does seem to work.
