Chrome version: 69.0.3497.21
OS: Chrome

Repro steps:
1. Check that Display Size for the internal display is set to something sane (like 1200x800 for my Pixelbook)
2. Enable Linux containers
3. sudo apt install simutrans
4. simutrans

Expected: The UI should be legible, or there should be some way to have 2x UI scaling.
Actual: The UI fonts were so tiny as to be illegible (and I'm in general a fan of tiny fonts!)

Notes:
xrandr has a way of scaling:
$ xrandr --output XWAYLAND0 --scale 2x2
but this isn't currently implemented in whatever Wayland Chrome OS containers use.
