Older Adreno drivers such as the 8 Gen 2's 0.676.1 lack
VK_EXT_external_memory_dma_buf, DRM modifiers and calibrated timestamps.
They failed device creation in the WSI layer, failed Proton games on the
zero-copy path, and corrupted the Steam UI under GPU compositing.
- WSI patch 0005 makes the Wayland platform optional per device, so a
device without its extensions stays usable for X11 swapchains instead
of failing vkCreateDevice.
- droiddeck-qualcomm-caps checks DMA-BUF export and import, the swapchain
extensions and Gamescope's linux-dmabuf once per session; Proton games
use the zero-copy WSI path only when it passes and stay on X11 SHM
otherwise. The session log records the verdict.
- The Steam browser uses software compositing when Zink offers less than
OpenGL 4.0, with BL_STEAM_CEF_SOFTWARE as the manual override.
Verified on the Adreno 740 (falls back to SHM and software compositing,
UI correct) and the Adreno 840 (zero-copy and GPU compositing unchanged).
