HiDPI scaling

[fieldse]

Hi there. Thanks for the awesome tool.
Having an issue with scaling on HiDPI screens.

Summary

App is tiny and unusable on high-resolution screens.

Problem description

On opening the app on a machine with a high resolution monitor, the app is tiny and unscalable, rendering the text and interface nearly impossible to see.

Expected behavior:
App should respect Qt scaling environment settings, and scale accordingly.

Actual behavior:
App interface does not change with environment settings

Attempted resolution

Attemped using QT scaling methods using environment variables as suggested in the ArchLinux HiDPI wiki (relevant to Ubuntu as well). These work for other QT apps, but do not work for Instagraph.

(See: https://wiki.archlinux.org/index.php/HiDPI)

Used settings:

• QT_AUTO_SCREEN_SCALE_FACTOR=1
• QT_SCREEN_SCALE_FACTORS=2
• QT_SCREEN_SCALE_FACTORS=2

Result:
Interface size has not changed.

System details

Platform: Ubuntu Linux 19.x
Screen resolution: 4K
