  + App.screen.resize = function(w, h, flags)

  + -- Hack. On Linux with LÖVE 12, I've observed love.window.setMode go awry.

  + -- Guidance from LÖVE folks (https://github.com/love2d/love/issues/2214)

  + -- is that everything should be working with density-independent units

  + -- most of the time, but on some platforms love.window.setMode doesn't do

  + -- so. In that case, make sure to pass in values in raw pixel units to it.

  + local w1 = love.window.getMode()

  + local w2 = love.graphics.getDimensions()

  + if w1 ~= w2 then

  + w, h = love.window.toPixels(w, h)

  + end

  + love.window.setMode(w, h, flags)

  + end
