I can't really say whether it's better or worse, with visible-bell t
on Windows the frame briefly flashes (with the FlashWindow function),
a bit like a flash in a terminal. Among the three visible-bell t
behaviors, it's the best one IMO, in the sense that it's visible and
not intrusive.
Is it possible to replicate on other systems?
It would be useful if someone could post a screenshot for those of us
with no access to any Windows machines.
I tried to do that, but it's not possible, it's a dynamic effect.
