Yeah, that could be called "broken by design". :-)

I never ever ever (un)plug a VGA cable on a live system. Not even on
laptops, where this is supposed to be safe. I had some very bad
experiences with doing that --- burnt graphics cards, burnt monitors,
burnt motherboards, etc. Since then I typically disconnect everything
from the power outlet before mangling video cables.

Best, :-)
