Weird superspeed in Geoscape

[TheQuinch]

I'm not sure what's the issue, but I've had a weird issue in Geoscape where scrolling the globe will sometimes just go completely haywire and the Earth will suddenly channel its inner pulsar. I initially thought it was something with my mouse, but now I'm not so sure. There's a screencap attachment for reference.

Edit: It also seems to reproduce with middle-mouse scrolling in battlescape.
Edit edit: I believe this was happening in the previous build as well.

I don't see what the issue is.
You could spin the globe at crazy speed since the beginning, both in OXC and OXCE.

Anyway, I don't use middle-button scrolling, since right-button is much more precise and convenient... so if anybody else noticed any change in scrolling behavior, do let me know.

Oh, that's the issue - I move the mouse at a regular speed, but then it will randomly just freak out for a second or two.

I remember, it happened to me as well; extremely rarely, though. Nothing that made me worry.
