Left panel automatically resizes itself to 50%

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Under certain conditions, the left panel of Cursor’s IDE automatically resizes itself to 50%. Manually resizing it becomes tiresome after it happens multiple times in a session.

Steps to Reproduce

  1. Manually resize the left panel to the size you want, let’s say 20% or so of the screen.
  2. Maximize the right panel (for me that’s usually Terminal) so that it fills up the rest of the screen.
  3. Open a file in the left panel.
  4. Observe that the third panel is opened properly with the file that was selected, but the left panel is now 50% of the screen rather than whatever size you set in step 1.

Expected Behavior

The left panel should always stay the size that I set it.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. This is a known issue that’s affecting many users on Cursor 2.0.x versions.

You’re running into the same panel resizing problem reported here: UI constantly resets layout in Cursor 2.0

I’ll pass your report along with the others so the engineering team can look into this regression. The specific trigger you found (opening files after maximizing the terminal) will be very helpful for debugging.
