What Should Happen?

the main content shows in full without clipping when side bar shown.

TL;DR

The issue can likely be resolved by adjusting the CSS styling to ensure the sidebar does not overlay the main content.

Guidance

  • Verify that the CSS rules for the sidebar and main content are correctly defined to achieve the desired layout, potentially involving position, float, or grid properties.
  • Check for any recent changes in the CSS files that could have introduced this regression, comparing the current version (1.2773.0) with the last known working version.
  • Inspect the HTML structure of the sidebar and main content to ensure it aligns with the expected layout, using developer tools in the browser.
  • Consider adding a temporary workaround, such as a CSS override, to push the main content aside when the sidebar is shown, until a permanent fix is implemented.

Example

No specific code example can be provided without access to the actual CSS and HTML code, but a potential fix might involve adding or modifying CSS rules similar to:

.sidebar {
  position: fixed;
  left: 0;
  top: 0;
  width: 200px; /* Adjust based on sidebar width */
}

.main-content {
  margin-left: 200px; /* Match the sidebar width */
}

Notes

The exact solution depends on the specific CSS framework and HTML structure used in the Claude Code application, which is not provided in the issue details.

Recommendation

Apply a workaround by adjusting the CSS to correctly position the sidebar and main content, as the root cause seems to be related to styling rather than a version-specific bug that could be fixed by upgrading.
