High GPU usage from Cursor and DWM on Windows 10 with WSL2

Bug Reports
1

Description:
Since version 0.51 and continuing into version 1.0, Cursor IDE has been causing extremely high GPU usage on my machine. After launching Cursor with cursor . from my WSL2 bash terminal, my GPU load spikes close to 100 percent. Task Manager shows about half of that usage from Cursor and the other half from Desktop Window Manager. When I close Cursor, DWM usage drops to zero immediately.

Steps to reproduce:

  1. Use Windows 10 with WSL2
  2. Launch Cursor from the WSL2 terminal with cursor .
  3. Give the agent something to do that involves code edits
  4. Repeat step 3 a few times
  5. Observe GPU usage in Task Manager

System info:

  • Windows 10
  • Cursor version 1.0 (problem started around version 0.51)
  • WSL2
  • All extensions disabled except WSL extension

Does this prevent you from using Cursor?
Yes. The GPU usage is so high that Cursor becomes almost unusable.
