minecraft-1.21.4-fabric-iris-bsl-esc-menu-854: Minecraft 1.21.4 Fabric +
Sodium + Iris + BSL 10.1.3 through Espryt on Mali-G77, paused at the ESC
menu over the BSL-blurred world, captured at 854x480 through the FCL
trace-capture skill. The trimmed trace keeps the whole session preamble
deliberately: the 107669b3 bug class is triggered while Iris BUILDS the
pipeline (a by-name texture call swapping the active unit's binding under
the sync memo), and the pause menu afterwards is where its damage is
legible - every glyph alpha-discards against the zeroed lightmap while
the button frames survive.
Ablation-proven as a net before landing: against a build with both layers
of 107669b3 reverted the case fails at ssim 0.949284 and the diff image
is text and only text - menu title, all button labels, the tutorial
toast; against the fixed library it matches the golden exactly, and
Magma passes the same golden at 0.998402 with no alternate needed.
Replays in about a minute per backend on llvmpipe/lavapipe (the 1.3M-call
preamble; well under the timeout and smaller than several existing
fixtures). Existing fixtures spot-checked green.
Two 1.21.1 NeoForge Create in-world captures facing water wheels and a
large cogwheel, one per flywheel backend (/flywheel backend indirect and
instanced). The indirect trace exercises the compute scatter/cull
pipeline, glMultiDrawElementsIndirect with GPU-written commands, and
draw-parameter emulation; captured with persistent-map shadowing so the
unflushed scatter descriptors Flywheel writes are recorded. Both trimmed
to a single frame and brotli-repacked (~7 MiB each).
