       root caused the backlight flicker (above certain brightness level which i clamped in firmware) on some pocket reform display v2 panels: the seller of the panels made this flex adapter for us to make the pinout compatible with the display v1 (eol, made by jdi), which has a pwm controller boost converter/led driver (?). the trace carrying 3v3 input supply is too flimsy for the potentially large currents. bypassing with a wire fixes the issue...
