Maybe. 'lazyredraw' may or may not fix this, I'm not sure.

So ignore autocmds while your script processes. Prefix it with :noautocmd or add stuff to 'eventignore'. Even built-in stuff like the preview window and the options window load the new window by opening a new window or jumping to the correct existing window, loading the content, and then switching back to the original window. If it's on the same tab page, you can use "wincmd p" to switch back. If it's on a different tab page, just switching back to the old tab page should leave you still on the same window, especially if you ignore the TabLeave/TabEnter autocmds.
