[0.6.9] Steam UI never appears on Mali-G1-Ultra (vivo V2545A / MT6993 / Android 16)

Client installs and starts fine (build 1792618285, zero downloads, GPU query OK, gamescope swapchain OK), but steamwebhelper crash-loops every ~10s (startcount 0->12) and no window is ever created: wayland.log shows "0 windows open | 0 window redraws | 0.1 fps" for the whole session.

Key evidence:

• steamui_html.txt: CreateBrowser id:... (-2147483648, -2147483648) 0x0, then RetryCreateBrowser ~1/sec, 20+ times, all failing — from t+2s after launch
• webhelper.txt: "Disabling sandbox due to a previous crash in CefInitialize"; ends with "Timed out waiting for webhelper init"
• console_log.txt: "Failed creating offscreen shared JS context"
• cef_log.txt: each PID stops at chrome_main_delegate.cc / bus.cc — dies in early CEF init
• session.log: "/tmp/dumps: insufficient permissions" — no minidump can be written
• exit codes across 4 sessions: rc=42 -> rc=134 (free(): invalid size) -> rc=139 (Segmentation fault)

Decisive negative experiment: BL_STEAM_SOFT_COMPOSITING=1 in droiddeck-env was fully applied (device.txt lists it; session.log "software CEF compositing"; steam args gained -cef-disable-gpu-compositing; webhelper cmdline really has --disable-gpu-compositing) — ZERO change. GPU compositing is not the cause.

Ruled out: downloads/updates (Nothing to do), memory (5.7GB free, crash buffer empty), display driver (Auto -> System Vulkan), user behaviour (failure at t+2s), custom PanVK drivers (none enabled).

steam args (hardcoded on arm64+Venus): -cef-force-gpu -cef-use-gl=angle -cef-use-angle=vulkan. BL_VKBRIDGE_CEF_* only applies on the bridge path (here bridge=false, venus=true); real -cef-disable-gpu seems reachable only via desktop mode (Desktop installed: false). GPU is flagged "Experimental" in device.txt.

Would help: (1) a switch to force -cef-disable-gpu or GL/software ANGLE in Big Picture/Venus mode; (2) fix /tmp/dumps permissions so a minidump can be written. Happy to test preview builds.

Attaching 4 Share logs zips (01 / 06 / 07 / 09; 09 is the switch-enabled run). All user-side - options exhausted. Thanks for the great work on DroidDeck!
