[qutebrowser] Some canvases hide cursor

[Ryan Roden-Corrent]

Are you on wayland, and if so, do you have an Nvidia card?
I've had issues with cursors appearing in applications like Blender,
which can be worked around by disabling hardware cursors.

Thats `WLR_NO_HARDWARE_CURSORS=1` on any wlroots compositor like Sway.
On hyprland it's

```
cursor {
    no_hardware_cursors = true
}
```
