Spring RTS Engine

I've had to turn off the single middle click behavior with "/set MouseDragScrollThreshold -1" because the panning is super jittery and reversed. It's like this in every Spring game, and every camera type.

I've tried:
Windowed and fullscreen.
V-sync on and off.
Reinstalling.

This is issue is known and going on for a while now

the jitter goes away when you use camera smoothing (widget) but the inverse movement stays

they have fixed the issue (in 104.0.1.681)

thnx for bringing this to attention
