System Information
Operating system: Windows 10 21H1 19043.2130
Graphics card: GTX1650 4GB

Blender Version
Broken: 3.5.0 Alpha, hash: 508fd044b4
Worked: 3.4.1, hash: ef9ca44dee

Short description of error
I'm using Blender through Windows Remote Desktop (RDP) for quite a long time.
Now in the new alpha 3.5 the Blender UI acts weird and non controllable anymore when using mouse middle click to pan viewport or left clicking into number fields to drag values up or down.

At this point for me Version 3.5 alpha is not usable anymore through an RDP connection - which is quite important for me! - while at least in Blender Version 3.4.1 everything worked fine!

Exact steps for others to reproduce the error

Open blender from a Windows computer on another Windows computer via remote session
use {key MMB} to pan viewport or {key LMB} into number fields to drag values up or down.

Are you using remote session between different OS (on .Mac and Windows)?
There are a couple related reports:
#102367 (Continuous Grab unexpected behavior when using remote connection)
#100438 (Cursor warping not supported on Remote Session)

I can reproduce in various severities on windows even as far back as 3.3 (likely earlier than that, but 3.3 is where i stopped testing) when you left click into number fields to drag values up or down which works ok, until you hit the right edge of the screen and the number jumps by thousands

however master starts jumping thousands right out of the gate even before hitting the screen edge, bisected to a somewhat messy history

the original commit that breaks this is 9fd6dae793
which gets reverted in 230744d6fd re-landed in f2945f3895 which then somehow breaks using the mouse to drag values up/down completely until 1a986f7eba reverts some other fix.... and it's back to the same behavior 9fd6dae793 introduced

This post on stack exchange seems to have a fun bit of information, that i can't seem to find any reference for on MSDN, but some preliminary testing does seem to imply it is true

If the mouse is hidden, the SetCursorPos interface will become invalid.

commenting out ::ShowCursor(FALSE) in GHOST_WindowWin32::loadCursor definitely improves the behavior (but it still acts wonky once the cursor wraps) so there's likely something to it..

@PrototypeNM1 any of this rings a bell for you?

@LazyDodo I don't recall anything particular re:ShowCursor, but this kind of jank doesn't particularly surprise me.
