What's Wrong?

When I open the sidebar a black blank space projects past the sidebar which then lays over top of the main work screen. Doesn't matter if I resize it doesn't matter if I go fullscreen doesn't matter if I open and close it.

What Should Happen?

The sidebar should not extend past where the sidebar actually is at least the overlay of it so there should be no extra black screen.

One open Claude Desktop go to the code section for me it's as simple as just opening the sidebar and then the black screen extends past the sidebar that's all I've had to do.

TL;DR

The issue can likely be resolved by investigating and adjusting the CSS styling or layout configuration of the sidebar in the Claude Code application.

Guidance

  • Review the application's CSS files to check for any recent changes or updates that may be causing the sidebar to extend past its intended boundaries.
  • Inspect the HTML structure of the sidebar and main work screen to ensure that the overlay is properly contained within the sidebar element.
  • Check for any JavaScript events or functions that may be modifying the sidebar's layout or position when it is opened or resized.
  • Verify that the issue persists across different Claude models and platforms to determine if it is a widespread problem or specific to a particular configuration.

Example

No code snippet can be provided without more information about the application's codebase, but a potential solution might involve adding CSS rules to constrain the sidebar's width or overflow.

Notes

The lack of error messages or logs makes it difficult to pinpoint the exact cause of the issue, and more information about the application's code and configuration may be needed to provide a definitive solution.

Recommendation

Apply a workaround by adjusting the CSS styling or layout configuration of the sidebar, as this is likely to be a quicker and more effective solution than waiting for an official fix, especially given that the issue is a regression and was previously working.
