System Information
Windows 10 64 bit, Intel i5 3570k, 16GB RAM, Nvidia 670GTX
Windows 10 64 bit, AMD-E2-1800, 4GB RAM, Radeon HD Graphics
3 Different mouses and a trackpad.
Blender Version
Broken: 2.77a, 2.78 4bb1e22

Short description of error
When using fly mode in 3D view, the view sometimes locks. After exiting the fly mode
and reentering it or alternatively simply by moving the mouse hard enough, it can unlock and start to move with the mouse.
However even if unlocked the view rotates into random direction even if the mouse is no longer moved.
Exact steps for others to reproduce the error
Seems to be directly linked to Windows 10's DPI system. When Windows 10's DPI scaling is changed without of restarting or having different DPI scaling between multiple monitors and using Blender on secondary monitor, causes this bug always to happen. I am fairly certain I have seen this bug happen without of changing DPI settings, however I am not able to reproduce the issues on those circumstances. To reproduce this bug, change Windows 10's DPI scaling as said above and simply open default scene with factory settings and go to fly cam mode by pressing shift+F in 3d View. After that the bug should happen.

Meh… we need some win10 AE dev here, @Sergey maybe? or @LazyDodo ?

I can't reproduce this problem on windows with blender 2.78a (even changing the DPI).
A better description of the steps to reproduce the problem is needed.

I will close the report since it is old and nobody else mentioned this problem.
It can be reopened if more information is provided.
