In-Game Graph Transparency Bug

Starting today i cannot move slider for transparency for the on screen graph, its either max or minimun....ofc everyone wants it at half...but doesnt work.

Checking the standalone PC client, it looks like the scaling is off for the slider.

I can still adjust it with some difficulty if I hold the mouse cursor toward the leftmost end of the slider (with the button down), but each small movement toward the right is scaled to a disproportionate effect.

It does not seem to be affected much by changing my mouse sensitivity (e.g., from 2500 to 1200 dpi) or window resolution.

Other settings sliders are unaffected.
