Current topic: "Configuring GPU Rendering for Regression Tests"
Topic summary: The user reminded me of a directive to always use GPU rendering for tests. I previously switched to software rendering (`angle_indirect`) due to a build failure, but I now need to investigate that failure and attempt to get hardware acceleration (`gpu=host`) working as requested. I will first read the full `TESTING_SETUP.md` for environment-specific guidance and then attempt to run the tests with the correct GPU settings.

Strategic Intent: I will re-evaluate the emulator's GPU configuration to honor the user's directive for hardware rendering, investigating the cause of the initial failure with `gpu=host` and attempting to resolve it.
