When using Ctrl+L to send code to agent, a blank space appears on the right side of the chat panel. This happens consistently when opening a new window and using the Send to Agent feature for the first time.
Steps to Reproduce
Open a new Cursor window
Press Ctrl+L to use the Send to Agent feature
Observe the blank space appearing on the right side of the chat panel
Expected Behavior
The chat panel should fill the available space without any blank area on the right side.
Operating System
Windows 10/11
Current Cursor Version (Menu → About Cursor → Copy)
I work across 10+ servers daily and often need to open new windows due to cache issues. This bug occurs every time I open a new window and use Ctrl+L for the first time.
It’s a recurring issue that requires manually dragging the panel each time, which disrupts workflow efficiency.
The blank space appears on the right when using Ctrl+L for the first time.
2. Reload Window behavior
I tested Reload Window. After reloading, the blank space does not appear.
But I found a reproducible pattern:
If a New Chat panel is already open → first Ctrl+L causes the blank space.
If New Chat is closed → first Ctrl+L does not cause the issue.
This happens every time.
3. Extensions disabled
I ran cursor --disable-extensions.
The issue still occurs.

Even if I am already chatting with the AI, using Ctrl+L for the first time in that window always creates the blank space.
The previous conversation doesn’t matter — the issue occurs as long as it’s the first use of Ctrl+L in that window.
