Navigating in Scene Viewport : problem !

Hi, everyone !!!
I have a problem that didn’t happened before:
now, when I try to ‘pan’ (move my view) inside the scene viewport : the movement is jerky/bumpy !
(when I say ‘pan’ I mean the hand icon in the “scene view”…)

consequence: the scene viewport is almost un-usable now !! I guess it is an issue/bug somewhere… I remember that Unity crashed this week (very rare thing, as I far I remember) … seems to be linked to this, cause now, this problem occurs but before everything was OK…

this is really annoying, I don’t know how to fix this, so please can someone help me ?!

thanks … :frowning:

I found out !!! before this I decided to put some prefabs far from the action, (because I just instantiate them) AND THEN:
the fact that some object where at 50 000 units away triggered this issue… so the solution is to not exaggerate with objects positions values IMHO …
