Switching to lowrezjam from custom solution, GUI scale is off

[greay]

using the custom.go for a 960x640 pixel game, I switched out my render script for the lowrezjam one and all the collections & tilemaps look great, but all of my GUI is enormous – it appears to all be rendered at at least 2x, leaving much of it offscreen.

Additionally, the touch targets appear to be for their "actual" position, not where they're rendered.

Hard to say what's wrong. If you can share (bjorn@defold.se) your project or a sample project showing this problem I'd be happy to take a look.

It's pretty easy to reproduce. I made a brand new project, only using Monarch and lowrezjam. Monarch's probably unnecessary, but it's what I'm using for all my GUI/scene transitions.

the sample project just has 1 collection with a GUI, and a single 240x240 box in the center of the screen. But with the project set to use the lowrezjam, the box is larger and somewhat offscreen.

I took a very quick look and it seems to happen when using a Retina screen (which explains the x2 size). I have not figured out a solution yet.

well I can use DefOS to query the scaling factor:

local displays = defos.get_displays()
local display_id = defos.get_current_display_id()
local modes = defos.get_display_modes(display_id)
-- pprint(modes[1]) -- Print information about the first available resolution mode
if modes[1].scaling_factor ~= 1 then
    print("screen scaling factor is "..modes[1].scaling_factor)
end

but I'm not exactly sure where to plug that info in

okay an update: setting "Adjust Reference" to disabled in my GUIs 100% fixed the visual sizing issue!

the mouse targets are still off, though.

An alternative approach would be to use the Orthographic camera with a fixed zoom. This way you get mouse input and everything else working out of the box. Here's an example:
