Why does the mouse become extra sensitive when dragging around inside blueprints?
If I hold down right click and drag across the blueprints grid window, my cursor travels the distance in a small fraction of the mouse movement which is normally required. It's like when I drag the grid around, my mouse sensitivity is very high. I have also noticed that the default camera rotation sensitivity in the viewport (2) feels very sensitive, and I have to go to the properties for each project and set the sensitivity to .05 to make it feel correct. Does UE4 not play well with high DPI mice? Currently my DPI is about 5k.
I have noticed that camera rotation sensitivity in the UE3 viewport is also much more sensitive than it should be.
My PC is Xenon Workstation with 12GB ram.
I'm using a Logitech G600.
When interacting with the viewport or the grid panel the cursor actually switches to a software cursor and reads the high precision data directly from your input device (aka mouse). This means that the input will feel different, generally faster, then when not interacting with these widgets. This is because it circumvents the OS mouse ballistics which slow the mouse down and produce "easing" effects depending on the speed you are moving.
This gives you 100% precision and allows us to perform endless scroll/pan type behavior, but has the negative side effect of generally slightly adjusting the cursor speed.
If you can adjust the speed of your mouse using it's drivers instead of relying on Windows mouse ballistics you should get a more consistent movement speed.
aka. open up the fancy mouse software you hopefully have installed and adjust the sensitivity there instead of in the normal Windows dialog. Sometimes you can adjust the sensitivity on the mouse hardware itself which should also do the trick.
Have you tried adjusting the camera move speed slider in the upper right corner of the viewport?
I have a high dpi mouse which I keep usually running around 3k-4.5k and have not had issues except when the camera speed is ramped up.

I'm still wondering if there will be some option to tweak the sensitivity inside the blueprints editor?
