Visual QA — GPU Backend
Each subdirectory contains one test category. Inside you will find:
README.org— what to verify and what failure looks liketest.el— loads the same scenario in GPU and vanilla Emacs for side-by-side comparison
How to run any test
Open two terminals. In the first, run the GPU version:
emacs --no-init-file -l qa/NN-name/test.el
In the second, run the vanilla baseline (GPU disabled):
EMACS_GPU_DISABLE=1 emacs --no-init-file -l qa/NN-name/test.el
Place both windows side by side and compare. Mark items in the README.org as PASS / FAIL / SKIP.
