For multible months now I encounter massive frame drops in raids when I use Z-Perl. If I disable Z-Perl, I am running on up to 120 frames in raids (I set max frames to 120). With Z-Perl on, it drops down to 22 at each boss, no matter which raid or boss.
I tried to narrow it down by disabling Z-Perl and then enabling it one by one, about half of the drop happens through raid and party frames. I really have no idea why this is happening, especially since the game itself runs smoothly with the addon disabled.

• Ever since the issue with Dispells popped up, I see uncurable debuffs on all my characters. (Priest suddeny sees curses etc, even with the option "only curable" checked.

Same, massive frame drops when ZPerl is on. Used bugsack addon but did not find any LUA errors. Really unfortunate as I love the addon and have been using it since X-Perl stopped being maintained.

Yes, I absolutely love ZPerl! Been using it ever since and I really don't want to stop.
There is no other addon which looks this good or has that many useful functions, so I hope there is a solution for this issue :(
I can provide details on my PC-setup if needed.
The more incoming information Z-Perl has to work with (raidgroups), the worse the frame drop gets for some reason
