What's Wrong?
Claude Code output shows blank lines instead of actual text content on Windows.
When I run any command, the response renders with excessive whitespace/blank lines. Only partial text is visible at the top and bottom of the response. The middle content is completely blank.
Tested on:
- PowerShell 7 (standalone)
- PowerShell 5 (Windows Terminal)
- VS Code integrated terminal
All have the same issue. UTF-8 encoding is confirmed (chcp 65001).
What Should Happen?
Output text should display correctly without blank lines

Same. After iterating a bit, it seems to be something about markdown because giving me a list of 10 things results in only the last one when it's doing what it normally does, but when I explicitly asked it not to use markdown in its reply the list was fine. This update is a big oof.
Temporary workaround. You can ask claude to write his whole answer in the last block/line. It seems that the last answer is visible constantly.
Same issue here
Yes, it seems that only the last line is visible. Thank you for the tip.
● Here's a random fact: Octopuses have three hearts. Two of them pump blood to the gills, while the third pumps it to the rest of the body. Interestingly, the heart that delivers blood to the body stops beating when the octopus swims, which is why they prefer crawling—swimming exhausts them.

I ran into the same issue.
Downgrading to 2.0.72 fixed it for me.
npm uninstall -g @anthropic-ai/claude-code
npm install -g @anthropic-ai/claude-code@2.0.72
