wlroots 0.20.2 (Arch's wlroots0.20, what the desktop's labwc links) gains an
allocator that exports Vulkan images as DMA-BUFs for a GPU node that is not a
DRM device - the Adreno KGSL stand-in - where gbm and the DRM lease path fail
('unable to create allocator'). linux-dmabuf skips its GEM import check on such
a node so client buffers are not all refused. Built by build-wlroots.yml.
Compositor: without a Wine desktop, a window that opens on top takes keyboard
focus (a gamescope started from the Linux desktop).
