Lagging issues? Every.single.time.
I used to think it was only when I posted images but I rarely, if ever, notice a difference now. It's not just a lag, the forum doesn't properly refresh more often than not and I end up closing the window and opening a new one. I mostly use the Brave browser.
It's been going on a while. The chartbuddy code has a delay coded specifically to compensate for it and that's years old.
