Major FPS loss during combat while Carb is enabled.

[shamby]

I have not seen my issue addressed. Many thanks to Rythal. Your work is greatly appreciated.
I am seeing fairly unplayable framerates (below 10) when engaged in combat while Carbonite is enabled. I have done everything I know to do regarding Carbonite-i.e.- deleting all files, reinstall, turn off all addons...etc. The FPS loss occurs when Carbonite is the lone addon enabled. When all addons are enabled but Carbonite - normal FPS loss occurs. There is no FPS issue when not in combat.
I would appreciate any insight as I have done pretty much everything I have learned throughout the years to 'fix' non-behaving addons. I will add that I am running Zorin 6 OS -64bit (Linux) and play no other games but WoW. Thanks.
