Yes. And if you had ever been in a paraglider yourself in a thermal
you would know that you often experience partial deflations. It is not
visible from the ground looking up, but it does happen and often.

Of course, some are trained enough to deal with partial
deflations..and some chutes are more resistant to them than others.

My statement stands though: If you thermal in a paraglider you *will*
experience deflations.
