Description

Description

GLUI is the only true interface for touchscreen, and tbh the scroll is atrocious.
It seems very insensitive. Just take any scrolling app or menu on a smartphone, and do a small finger swipe : the menu will go pretty far.

On GLUI, even a huge swipe is slow. It really should be fixed. At least, to begin, a "scroll sensivity" option would be very welcomed.

Research direction

The issue identifies GLUI scrolling on Android and Nintendo Switch but names no source file, entry point, or test. Trace the touchscreen scrolling behavior and compare small swipes with the expected smartphone-like movement; done means scrolling is more responsive, potentially with a configurable sensitivity option.
