front_end = "OpenGL"

Specifies which render front-end to use. This option used to have more scope in earlier versions of wezterm, but today it allows two possible values:

  • OpenGL - use GPU accelerated rasterization (this is the default)
  • Software - use CPU-based rasterization.

You may wish (or need!) to select Software if there are issues with your GPU/OpenGL drivers.

WezTerm will automatically select Software if it detects that it is being started in a Remote Desktop environment on Windows.
