Research direction

Start by reproducing the canvas drawImage performance problem in vanilla Hyper.app on Windows 10 and review the linked Electron issue #11051 alongside the supplied DevTools evidence. Done would require identifying a confirmed Hyper-side fix or workaround; the payload names no Hyper file or test to change.
