Sway HiDPI settings (GTK/QT/Sway) - How to

set $cursor_size 54

```
# GTK
# This is the only place where you must set GTK scaling
set $gnome-schema org.gnome.desktop.interface
exec_always {
    gsettings set $gnome-schema gtk-theme 'Matcha-dark-sea'
    gsettings set $gnome-schema icon-theme 'Numix-Square'
    gsettings set org.gnome.desktop.interface text-scaling-factor 2.73
    gsettings set org.gnome.desktop.interface cursor-size $cursor_size
}

# QTK SCALING
# See:
# ~/.zshrc and
# ~/.local/bin/wofi-hidpi
```

That's the important part. With that sway config alone you should have fixed almost everything. The only thing left is to fix QT applications:

.zshrc
```
# DESCRIPTION: This will apply the right size to the QT/Java programs you open from terminal.

export QT_AUTO_SCREEN_SCALE_FACTOR=0
export QT_SCALE_FACTOR=2.7 export ELM_SCALE=2.7

```

~./local/bin/wofi-hidpi
```
# DESCRIPTION: From now on, you call rofi using this binary. This way any QT/Java progam you open will have the right env vars applied (without having to source your entire zshrc, which would make wofi noticeable slow)
export QT_AUTO_SCREEN_SCALE_FACTOR=0
export QT_SCALE_FACTOR=2.7 export ELM_SCALE=2.7 exec wofi
```
Things to consider

* On wayland, apps can decide the mouse cursor. For exacple: To this date, running google-chrome-beta in wayland mode, will make the cursor tiny. Just wait untill they fix it.
* If my method is too hard for you, you could just set scaling for your monitor instead, which is way easier to setup.
