It's not just CTRaid. Several guildies and I were having problems with this, we tried disabling addons, some even did full, clean reinstalls, and the error keeps occuring. In fact, it seems even worse with the stock blizz UI.
The one "fix" I have seen so far is to download Perl Classic. That cuts about 95% of the problems. I still have issues on my hunter or warlock with my pet bars disappearing randomly or just not showing up in the first place, but it reduces the amount that the targetting bug occurs dramatically.
What's really odd is that on my druid, I wont get a target frame, but my combo points will still show up, with me having no way to tell what they're on.
Other unresolved issues:
Raid promotions/leader changes going to random raid members.
Kicking people from raid kicks a random person.
Raid buffs not showing up properly when targetting someone outside your party.
Buff icons not displaying properly for buffs.
