Certain Windows GPU drivers can make pages combining "frosted glass" blur, WebGL, and a blinking text cursor flicker while the window has focus. If you see this:

  1. Try the built-in Glass Blur Deflicker plugin (☰ → Plugins…) first — it targets exactly this without changing your graphics mode.
  2. If that's not enough, switch to Compatibility graphics mode: Graphics modes. Vodou will offer to restart to apply it, silently reopening your tabs.
  3. As a last resort, Software mode disables GPU rendering entirely — most stable, but slower.
