Question: Again a reascript question (sorry about that): What is the proper way to support retina/hidpi in scripts? We tried to figure it out, but I think nobody has got it 100% right yet. forum.cockos.com/showthread.php?t=230120

    the proper way is to set gfx.ext_retina to 1 at script start, then after gfx.init() check it to see if is set to a value greater than 1. It will be automatically updated based on the monitor that contains your window.

    So, in order to set the size of the gfx window according to the retina scale, do I have to gfx.init, gfx.quit, get the scale and then gfx.init with the correct width and height? Or is there any other way to set the correct gfx window size according to the scale?

    It's undocumented (I'll update the docs!) but if you call gfx.init("",w,h) it will resize the window. Of course, you don't want to scale on macOS, because its units are independent of DPI (sanity!) -- so you want to do os = reaper.GetOS() if os ~= "OSX64" and os ~= "OSX32" and os ~= "macOS-arm64" then ...

    gfx.init("", width, height) seems to resize indeed, but after the resize nothing is drawn if the the script is not deferring. But even if it is deferring, gfx.drawstr seems to not work (I can send you some test code if you want)... Regarding macOS, does this mean that there is no need to scale the size of the gfx window? It will be done automatically? And I need to scale only the contents? Did I understand right? Thanks!
