I'm continually surprised that display systems don't implement safeguards designed to minimize this sort of thing.

It seems like it should be relatively simple to prevent repetitive flashing patterns from ever occurring by tracking the last few seconds of display state and looking for blinking regions of the screen. This would fix the problem for all applications, including blinking caused by something like scrolling too fast through a task switcher.

If I were epileptic I would want something like this for my computer as a layer of safety.
