Yes and no.
What i mean: I know that it theoretically uses memory but lua should menage it so it doesn't grow that rapidly. In same code i do

chatTab:HookScript('OnEnter', function(self) newFrame.hover = true updateTabColors(newFrame) end)

Which fires every time i mouse over chat tab, and is definetly more complex that function() end right? But my addon memory doesn't even twitch while I'm hovering those tabs in/out like madman

But in just 15s with this flawed code from first post i can go well over 1 MiB in resource tools memory usage. So there is definitely something terribly wrong.

Edit:Thanks mrruben5!
