[BUG] Claude Desktop Windows - Window cannot be resized below minimum width (regression, last 2 days)

Preflight Checklist

• I have searched existing issues and this hasn't been reported yet

• I am using the latest version of Claude Code

What's Wrong?

Within the last 2 days, the Claude Desktop window can no longer be resized below a certain minimum width. The exact version that introduced this regression is unknown, but it was working correctly before that. This makes the app unusable in split-screen mode on a portrait-oriented display.
No changes were made to display settings, resolution, or scaling on the machine. All other apps resize normally.

What Should Happen?

The window should be freely resizable to any width, as it was previously.

It seems indeed like the same thing but I am on Claude Destop Windows, so it may be better for the support to see this issue too

The new update today didn't resolve this on Mac.

Same thing on Claude 1.3561.0 (fbc74b) 2026-04-20T14:59:51.000Z for windows

The new update released today did not fix the issue either. I am still unable to reduce the width of the Claude for Mac desktop app below 600px.
