OS: Windows x64, Win 7 Pro SP1
Brave version: 0.25.2
Notes: Brave updated a few days ago, and had been operating normally.
Steps: I opened a new tab this morning, and the browser went entirely white. The browser did not respond to typical keyboard or mouse commands. I closed Brave with the task manager and restarted; the screen was still white. I tried running with --disable-gpu and --ignore-gpu-blacklist options, individually and in combination; the screen was still white. I closed Brave with the task manager, and ran Update.exe; the screen was still white. I closed Brave with the task manager, uninstalled and re-installed; the screen was still white. I uninstalled, cleaned the registry manually, and reinstalled; the screen was still white.
