Poor performance on OSX

[xnite]

I'm a bit new to Mac (just set it up a couple of days ago in fact), but I have HexChat setup and when my HexChat window is up on both my PC & my Mac I'm noticing that there is a few seconds delay before the text hits my Mac's client.
Both clients are connected to my ZNC server & both computers are hardwired to my network. There is no lag being reported by the client & the delay seems to be caused more so by the software than network connection. These delays can also be noticed with text being sent out, when I press the enter key it takes about a second or so before the text shows up in the main chat view, though it is instantly on my Windows client screen.
I however can't be certain this is an issue particularly with the HexChat software or Mac itself. If I could run any tests to help better determine the cause of such a delay feel free to let me know & I will run them.

The text widget HexChat uses is custom and some of its performance 'hacks' do not work on OSX. On top of that cairo/gdk/whatever seems to be slower in general on OSX. So it adds up to an extremely laggy experience that is not an easy thing to solve.

@TingPing that's understandable, and it's a much better bug than most of the applications I have been trying to use (Gedit for example crashes everytime I try to resize the window), so the fact that it's even usable on Mac is good :)

@xnite Unrelated but what version of gedit? 3.13 has had a ton of work done to it for a fairly solid osx release

It may or may not be directly related, but even on Windows some slowness can be encountered on a reasonably recent (5 years old) laptop. I noticed slowdowns in text rendering when another application is doing constant almost-fullscreen updates and rather extreme performance breakdowns when dragging another window over HexChat. With a 1920x1200 fullscreen window and power saving mode enabled (I think the CPU is clocked around 800 MHz in that case), updating the complete IRC window takes maybe half a second and I can see every line being rendered separately.
Maybe it would already help to lock the drawing surface during rendering? The fact that I can see every line being rendered separately kinda gives me the impression at a lot of unnecessary on-screen blitting is being done, so making sure that everything is rendered in an off-screen buffer might help.

@sagamusix Yes, xtext is terrible and yes it should do that. I personally see no reason to fix xtext instead of just using a standard textview..

Any news on this bug? I just installed Hexchat on my Mac for the first time and noticed this as well.

Issue still remains, fresh install OS X 10.11
