[QGIS-Developer] Weird navigation issues in 3d view on Windows

[Andreas Neumann]

Hi,

I recently had to switch my main laptop from Linux (previous employer) 
to Windows (new employer) - and with my new laptop I have very strange 
issues when navigating in 3D views in QGIS (tested with 3.28.7 and 
3.30.3 and master):

  	* the steps when navigating in the scene (left mouse button) are 
extremely small. When dragging the mouse substantially, only very tiny 
differences are visible in the 3d camera movement. When moving the mouse 
far, it would move a tiny bit and then suddenly "jump back"
  	* the middle mouse button which would normally rotate the whole scene 
now acts in "look around" mode
  	* zooming in and out with the third mouse button appears to have the 
same tiny steps like when navigating with the left mouse button
  	* changing the "movement speed" in Menu "Settings" --> "Options" --> 
"3D" doesn't improved things. Even when setting it to the maximum 
"99.9999", the steps for each movement are extremly tiny

Any idea how to improve the situation? Did others run into similar 
issues?

I initially thought that it might have something to do with the high 
resolution of the system (4k resolution) - but even when reducing the 
display resolution, the problems would remain.

The same project would work just fine on my previous Linux laptop.

Thank you for any hints on what could be wrong on my new Windows system?

Andreas
