AFAIK, yes. Doing what you did (a) disables all possible display
optimizations that the redisplay engine has up its sleeve to speed up
the common cases, and (b) forces Emacs to traverse the 10000 text
properties for each character it is about to display.

I don't know of any, except ``don't do that'', but perhaps Kim or
Stefan will.

It's because even cursor motion, that usually takes a fast shortcut
through the redisplay code, requires to search all the text properties
in your situation.
