Issue description

This issue only happens in examples (eg. models_mesh_picking) which have mouse middle button based pan and orbit. It has two problems-

1. Clicking the middle button to pan the camera is sending camera in the left direction at very high speeds.
2. Clicking ALT and then middle button to allow orbit camera around an object will spin your camera at Y axis infinitely.

Environment

Raspbian buster (32bit) running on RPI02W.

Issue videos

1. Camera pan away problem: (No video, couldn't click the buttons and take the video) But it reproduces 100%

2. Spinning problem: https://user-images.githubusercontent.com/7444189/186029419-1775fd6a-3422-4d93-ada5-cabd4885df81.mov

Code Example

Just run make with PLATFORM_RPI or PLATFORM_DRM and pick any example which allows you to use the middle mouse button to pan around and rotate/orbit the camera around that object. I tried with different mice - bluetooth and wired - same result.
