Split terminal multiple times very slugish

I do not think this is conected to dom rendering of the terminal.
Open terminal:
Click on the split termianl like 10 times very fast -> whole vscode is slugish for the next minute and there are some visual glitches.
If this action is so heavy I would expect that it gets disabled while a new terminal is initatialising

I can't seem to repro a particular perf problem on mac or Windows, there's a slow down for a few seconds which is expected but everything is fine after that. I do notice some glitches on mac which might be worth looking into though.

This might also be connected to the fact that I use zshell

@isidorn oh-my-zsh?

That shouldn't affect perf while idle though 😕

[isidorn]

@Tyriar yes

Closing this as there isn't really a fix that I'd want to do apart from improving the speed of the terminal (which is something that's always being looked into). Disabling the action while split is happening would be annoying as I often quickly hit ctrl+shift+5 twice to split twice.
