Please add an scale setting (HIDPI support)

[Zeioth]

Is your feature request related to a problem? Please describe.
Waydroid works good, but apps look tiny on my 4k screen, which in practice makes them unusable.

Describe the solution you'd like
Having an env var like WAYDROID_SCALE=2 to scale the window content, like most apps work .

Describe alternatives you've considered
A waydroid prop for the same purpose.

Honestly i don't know the dpi value which is equivalent to hidpi so just set the value as you like.

# Remove ro.sf.lcd_density properly if exist
grep ro.sf.lcd_density /var/lib/waydroid/waydroid_base.prop && \
sudo sed -i '/ro.sf.lcd_density/d' /var/lib/waydroid/waydroid_base.prop

# Append ro.sf.lcd_density property
echo "ro.sf.lcd_density=320" | sudo tee -a /var/lib/waydroid/waydroid_base.prop

Then restart waydroid.

Please read this too #388 (comment)

So we do have a prop for it!! It would be nice to add it to the docs.

It worked perfect, thank you so much.

yeah this is true. this issue should stay open until it is addressed

There already is GRID_UNIT_PX

Also I don't know how but on my HiDPI laptop it's nicely scaled out of the box?

Your compositor should be reporting the wayland display scale. If not, you can use export GRID_UNIT_PX= or other ways as pointed out.
