WebGPU tests that require manual intervention.Many of these test may be HTML pages rather than using the harness.Add informal notes here on possible stress tests.- Suspending or hibernating the machine.- Manually crashing or relaunching the browser's GPU process.- Triggering a GPU driver reset (TDR).- Forcibly or gracefully unplugging an external GPU.- Forcibly switching between GPUs using OS/driver settings.- Backgrounding the browser (on mobile OSes).- Moving windows between displays attached to different hardware adapters.- Moving windows between displays with different color properties (HDR/WCG).- Unplugging a laptop.- Switching between canvas and XR device output.TODO: look at dEQP (OpenGL ES and Vulkan) and WebGL for inspiration here.
