Not Scaling UI to High DPI Screens

[FoilBlue]

got a gpd pocket. which has a 1080p 7inch screen! wanted to have kontalk on it but its not really usable, as UI too small. not yet found a working workaround.
i have tried: https://wiki.archlinux.org/index.php/HiDPI#Java_applications

maybe its something i need to do to my system. idk. thought i would give heads up.

Additional information

Kontalk Desktop version:3.1.2
Operating System:gnu/linux ubuntu
Desktop Environment: gnome 3 (if using Linux)
Kontalk Android version: (if Android device is involved)

I believe this is really an OS issue. I mean you should act on the pixel density factor on your graphical environment. I don't think we can do anything but redesigning the user interface for e.g. a touch device, which is completely different from a desktop device.

@abika any thoughts/comments?

For Linux, Java applications might use an environment variable that you can set:
export GDK_SCALE=2
before starting the program from the Terminal.
For the Kontakt desktop client on a Ubuntu 18.04 on a high dpi screen, this works.
