Sister script of dev-ultra-restore.sh. Runs `npm run tauri dev` with the full degraded-rendering env applied so the SW path can be exercised even when the persisted graphics_settings DB has HW accel enabled. Useful for testing the modal mount cost, splash spinner smoothness, and Discovery V2 paint cost under WebKitGTK without GPU. Sets five env vars: QBZ_HARDWARE_ACCEL=0 (QBZ's own nuclear opt-out) WEBKIT_DISABLE_COMPOSITING_MODE=1 WEBKIT_DISABLE_DMABUF_RENDERER=1 GSK_RENDERER=cairo (GTK4 SW renderer) LIBGL_ALWAYS_SOFTWARE=1 (Mesa llvmpipe) Flags: --no-kill skip stale-process cleanup --print print the env vars and exit (for sourcing) cc

# Force QBZ to run under software/CPU rendering across every layer that
|
|
# can sneak the GPU back in. Useful for testing the degraded paint path
|
|
# (modal mount cost, Discovery V2 perf, etc.) without touching the
|
|
# persisted graphics_settings DB. Sister script of dev-ultra-restore.sh.
|
|
#
|
|
# Layers forced off / to SW:
|
|
# QBZ_HARDWARE_ACCEL=0 — QBZ's own nuclear opt-out
|
|
# (overrides graphics_settings DB)
|
|
# WEBKIT_DISABLE_COMPOSITING_MODE=1 — WebKit redraws via SW compositor
|
|
# WEBKIT_DISABLE_DMABUF_RENDERER=1 — no DMA-BUF GPU texture sharing
|
|
# GSK_RENDERER=cairo — GTK4 picks the cairo SW renderer
|
|
# (Vulkan / GL paths disabled)
|
|
# LIBGL_ALWAYS_SOFTWARE=1 — Mesa GL falls back to llvmpipe
|
|
#
|
|
# Usage:
|
|
# bash ./scripts/dev-cpu-mode.sh # kill stale + start tauri dev
|
|
# bash ./scripts/dev-cpu-mode.sh --no-kill # skip process cleanup
|
|
# bash ./scripts/dev-cpu-mode.sh --print # print the env vars and exit
|
|
# (for sourcing into another shell)
