Describe the bug

Changing the opacity slider will fade out the theme's background to reveal a pitch black background underneath, rather then adjusting the window's opacity. 'Window Blur' button ineffective.

To reproduce

Fresh Warp install, NVIDIA desktop GPU, no integrated graphics, any backend. Issue reproduced on laptop with integrated graphics.

1. Open Warp.
2. Navigate to appearance inside of options.
3. Tweak opacity knob. 'Window Blur' button has no effect.

Expected behavior

Expected window background opacity to change, revealing desktop and windows underneath, akin to behavior on Mac OS.
