what to do when a view gets longer than the screen as it flickers badly on updates

[KyleAMathews]

Is there any easy way to detect when this is happening so we can take corrective measures?

[vadimdemedes]

Hm, not really, this is up to your terminal to render the text, so the flickering is on them. For example, while iTerm may flicker, built-in terminal app in macOS almost never does.

As for the code here, what is the UI supposed to do? I will probably be able to help better if I'm more familiar with your use case.

We noticed in our app (gitgud) that iTerm2 would cause it to become almost unusable due to flickering. If you switch terminals to hyper or the default mac terminal it will almost completely fix the issue. I think it is just an iTerm2 bug.

FWIW, I feel like lately iTerm2 has been having issues like this that are definitely unrelated to Ink. Just streaming significant of output in general has been weird. Maybe the most recent update had a bug or something?

Hello,

I'm having issues running my application in "fullscreen" on iTerm. The screen is flickering really badly when there are a lot of updates to the screen. It seems as iTerm queues up all the frames and shows them one by one instead of just showing the latest frame.

My application is a circle-ci dashboard. I was inspired by k9s (https://github.com/derailed/k9s) which runs really smoothly on iTerm (written in go though). Have a look at my project to see if you can find any gotchas:

It seems to be an iTerm issue. Try using a different terminal.

[marcus13371337]

Yes, it's definitely an iTerm issue, however, if I were to distribute my cli I want it to run smoothly in every terminal. Since there are applications running smoothly on iTerm (k9s as an example), I guess there are some hacks/features ink can implement in order to make the iTerm experience better

[marcus13371337]

Think I found a solution to the problem which I've presented in the following PR:
#413

@H3RSKO Would you be super kind to try it with gitgud in iTerm and confirm that it fixes the flickering, would be super nice. It's not 100% bug-free though

For me this happens in mac default terminal as well (using oh-my-zsh) as soon as I set main container Box height to process.stdout.rows and update any part of the content (happens in iTerm as well)

[royshouvik]

The changes in the linked PR drastically improves the flickering in iTerm for me. Although I needed to make the box height 1 less than process.stdout.rows.

Just chiming in to say that I had the same problem on Windows, and @royshouvik 's solution worked for me as well for Windows Terminal both cmd and PowerShell. Thank you for the tip!

Is there plans to still merge the POC or something more polished (if needed)?
