Mouse control problem with Remote Desktop Connection (windows) about fluidx3d

@ProjectPhysX I took mouse_sensitivity = 0.01. It looks like the reaction is getting slower but I still cannot control a view angle properly.

Hi @rodionstepanov,

thanks for reporting this. It's the age-old poor design choice of Microsoft's SetCursorPos itself triggering a WM_MOUSEMOVE event, when setting the cursor back to the center of the screen. Usually in my implementation this is not an issue, as screen_width/2 ad screen_height/2 are subtracted and the resulting movement upon cursor centering is 0/0.

However, in another poor design choice by Microsoft, when the remote screen resolution is different and/or off-set compared to the client screen resolution, SetCursorPos(width/2, height/2) works on client and the reported position from WM_MOUSEMOVE is on remote, and when they mismatch, it adds the off-set mouse movement 60 times a second and rotates the camera very fast.

I have now changed the mouse input routine on Windows to avoid WM_MOUSEMOVE alltogether. Please test this new version on your remote setup and tell me if it resolves the bug!

Kind regards,
Moritz

I'm sorry but it does not resolve the bug. I've test with setup for 3D Taylor-Green vortices; Looks like sensitivity is very high.

@rodionstepanov can you try if reducing the mouse_sensitivity constant helps?
